Scope.
Over the last four decades Peter Jones has demonstrated the power of using ideas from real and harmonic analysis to solve difficult problems in complex and functional analysis, geometric measure theory, conformal dynamics, conformal probability and geometrically based applied mathematics.
Although much of this work is highly technical, it is usually motivated by simple geometric or analytic ideas.
The conference will explore the areas listed above from the perspectives of both established experts and younger researchers, with an emphasis on interactions between areas and the basic themes that recur in each of them.
Specific topics will include recent advances in harmonic measure, SchrammLoewner Evolutions (SLE), Gaussian Free Fields (GFF), rectifiability, and the analysis of big data.

Titles and Abstracts
Monday: SLE/Math Physics
Stanislav Smirnov (University of Geneva, St. Petersburg University): Clusters, loops and trees
We will report on our ongoing work with Antti Kemppainen aimed at describing geometrically the scaling limit of the critical Ising model.
Bertrand Duplantier (Institute for Theoretical Physics, ParisSaclay University): CLE Exteme Nesting and Liouville Quantum Gravity
We describe recent advances in the study of SchrammLoewner Evolution (SLE), a canonical model of noncrossing random paths in the plane, and of Liouville Quantum Gravity (LQG), a canonical model of random surfaces in 2D quantum gravity. The latter is expected to be the universal, conformally invariant, continuum limit of random planar maps, as weighted by critical statistical models. SLE multifractal spectra have natural analogues on random planar maps and in LQG. An example is extreme nesting in the Conformal Loop Ensemble (CLE), as derived by Miller, Watson and Wilson, and extreme nesting in the $O(n)$ loop model on a random planar map, as derived recently via combinatorial methods. Their respective large deviations functions are shown to be conjugate of each other, via a continuous KPZ transform inherent to LQG.
Joint work with Gaetan Borot and Jérémie Bouttier.
Nikolai Makarov (Caltech): Etudes for the inverse spectral problem
Steffen Rohde (University of Washington): Conformal laminations and trees
Conformal maps $f$ of the unit disc $D$ have a continuous extension to the circle if (and only if) the boundary of the image $f(D)$ is locally connected. This extension induces an equivalence relation on the circle by declaring that $x \sim y$ if $f(x)=f(y).$ Which equivalence relations on the circle arise in this way? After a brief discussion of the history and motivation, I will present a characterization under the additional assumption that $f(D)$ is a John domain whose complement has empty interior.
Dapeng Zhan (Michigan State University): SLE loop measures
We use Minkowski content (i.e., natural parametrization) of SLE to construct several types of SLE$_\kappa$ loop measures for $\kappa\in(0,8)$. First, we construct rooted SLE$_\kappa$ loop measures in the Riemann sphere $\hat{\mathbb C}$, which satisfy Möbius covariance, conformal Markov property, reversibility, and spacetime homogeneity, when the loop is parameterized by its $(1+\frac \kappa 8)$dimensional Minkowski content. Second, by integrating rooted SLE$_\kappa$ loop measures, we construct the unrooted SLE$_\kappa$ loop measure in $\hat{\mathbb C}$, which satisfies Möbius invariance and reversibility. Third, we extend the SLE$_\kappa$ loop measures from $\hat{\mathbb C}$ to subdomains of $\hat{\mathbb C}$ and to two types of Riemann surfaces using Brownian loop measures, and obtain conformal invariance or covariance of these measures. Finally, using a similar approach, we construct SLE$_\kappa$ bubble measures in simply/multiply connected domains rooted at a boundary point. The work answers a question raised by Greg Lawler.
Eero Saksman (University of Helsinki): On Gaussian multiplicative chaos and the Riemann zeta function
We recall some basic properties of Gaussian multiplicative chaos and describe our recent results on its connection to the functional statistics of the Riemann zeta function on the critical line (and to that of random unitary matrices). The talk is based on joint work with Christian Webb (Aalto University).
Tuesday: Complex/Real/Harmonic Analysis
John Garnett (UCLA): Many Theorems and a Few Stories
Jonas Azzam (University of Edinburgh): The Analyst's Traveling Salesman Theorem for large dimensional objects
The classical Analyst's Traveling Salesman Theorem of Peter Jones gives a condition for when a subset of Euclidean space can be contained in a curve of finite length (or in other words, when a "traveling salesman" can visit potentially infinitely many cities in space in a finite time). The length of this curve is given by a sum of quantities called betanumbers that measure how nonflat the set is at each scale and location. Conversely, given such a curve, the sum of its betanumbers is controlled by the total length of the curve, giving us quantitative information about how nonflat the curve is. This result and its subsequent variants have had applications to various subjects like harmonic analysis, complex analysis, and harmonic measure. In this talk, we will introduce a version of this theorem that holds for higher dimensional objects other than curves. This is joint work with Raanan Schul.
Alex Iosevich (University of Rochester): Group actions, Mattila integral and simplexes inside fractal sets
We will describe how a simple group action viewpoint can be used to derive the classical Mattila integral and to study the distribution of simplexes inside compact subsets of Euclidean space of a given Hausdorff dimension. More general configuration are studied as well where the various notions of rigidity come into play along with Sard's theorem. A variety of interesting model multilinear variants of generalized Radon transforms arise in this context and we shall discuss some steps towards the general theory of these objects.
Maria Cristina Pereyra (University of New Mexico): Weighted inequalities and dyadic harmonic analysis
In this talk we survey the interplay between dyadic techniques and weighted inequalities. This interplay has led, among others, to the solution of the A2 conjecture by Hytönen and the two weight problem for the Hilbert transform by Lacey, Sawyer, Shen, and UriarteTuero.
Michael Benedicks (KTH): Almost sure continuity along curves traversing the Mandelbrot set
We study continuity properties of dynamical quantities while crossing the Mandelbrot set through typical smooth curves. In particular, we prove that for almost every parameter $c_0$ in the boundary of the Mandelbrot set $M$ with respect of the harmonic measure and every smooth curve $\gamma:[1,1]\mapsto {\mathbb C}$ with the property that $c_0=\gamma(0)$ there exists a set ${\mathcal A_\gamma}$ having $0$ as a Lebesgue density point and such that that $\lim_{x\to 0} \mathrm{HDim}(J_{\gamma(x)}) = \mathrm{HDim}(J_{c_0})$ for the Julia sets $J_c$. This is joint work with Jacek Graczyk.
Mikhail Sodin (Tel Aviv University): Translationinvariant probability measures on entire functions
I shall speak about a somewhat unexpected and wild object: the probability measures on the space of entire functions (of one complex variable) which are (a) invariant with respect to the action of the complex plane by translations, and (b) do not charge the constant functions. The existence (and even an abundance) of such measure was discovered by Benjy Weiss.
The talk will be based on the joint work with Lev Buhovsky, Adi Glucksam, Alexander Logunov, arXiv:1703.08101.
Wednesday: Probability/Applied Math
Krzysztof Burdzy (University of Washington): On the number of collisions of billiard balls
In lieu of an abstract I offer a problem. Consider three billiard balls of the same radius and mass, undergoing totally elastic reflections on a billiard table with no walls (the whole plane). All three balls can be given nonzero initial velocities. What is the maximum (supremum) possible number of collisions among the three balls? The supremum is taken over all initial positions and initial velocities. I will discuss this problem and its generalization to any finite family of balls in one, two and higher dimensions. Joint work with Mauricio Duarte.
Maria Jose Gonzalez (University of Cadiz): A limit theorem for random games
We will apply techniques which arise in the context of Fourier Analysis on Boolean functions to study the behavior of the iterates of a special kind of functions, called selectors, acting on random variables. Our main motivation comes from game theory, however selectors appear in many different contexts, such as elections or noisy computations. Joint work with F. Durango, J.L. Fernandez and P. Fernandez.
Mauro Maggioni (Johns Hopkins University): Multiscale Geometric Methods for high dimensional data near lowdimensional sets
We discuss a family of ideas, algorithms, and results for analyzing various new and classical problems in the analysis of highdimensional data sets. These methods we discuss perform well when data is sampled from a probability measure in highdimensions that is concentrated near a lowdimensional set. They rely on the idea of performing suitable multiscale geometric decompositions of the data, and exploiting such decompositions to perform a variety of tasks in signal processing and statistical learning. In particular we will discuss the problem of dictionary learning, of regression, of learning the probability measure generating the data, and efficiently computing optimal transportation plans between probability measures. These are joint works with W. Liao, S. Vigogna and S. Gerber.
Thursday: Harmonic Analysis/PDE
Nets Hawk Katz (Caltech): Improved Hausdorff dimension bounds for Kakeya sets in $\mathbb{R}^3$
We show that for a uniform $\epsilon>0,$ Kakeya sets have Hausdorff dimension $5/2 + \epsilon.$ This is joint work with J. Zahl.
Ilia Binder (University of Toronto): Uniqueness and almost periodicity in time of solutions of the KdV equation with certain almost periodic initial conditions
In 2008, P. Deift conjectured that the solution of KdV equation with almost periodic initial data is almost periodic in time. I will discuss the proof of this conjecture (as well as the uniqueness) in the case of the socalled SodinYuditskii type initial data, i.e. the initial data for which the associated Schroedinger operator has purely absolutely continuous spectrum which satisfies some regularity conditions. In particular, it applies to small analytic quasiperiodic initial data with Diophantine frequency vector. This is a joint work with D. Damanik (Rice), M. Goldstein (Toronto) and M. Lukic (Rice).
Stefan Steinerberger (Yale University): Brownian motion and PDEs
Classical Brownian motion sheds an interesting light on the theory of elliptic partial differential equations  I will discuss various recent new results that strenghten/simplify/improve some classical results and point towards new problems. The main point of the talk is that all the Brownian motion arguments are quite simple and flow naturally (Brownian motion helps you drift in the right direction).
Aleksandr Logunov (Tel Aviv University, Chebyshev Laboratory): $0.01\%$ improvement of the Liouville property for discrete harmonic functions on $\mathbb{Z}^2$
Let $u$ be a harmonic function on the plane. The Liouville theorem claims that if $u$ is bounded on the whole plane, then $u$ is identically constant. It appears that if $u$ is a discrete harmonic function on the lattice $\mathbb{Z}^2,$
and $u$ < $1$ on $99.99\%$ of $\mathbb{Z}^2,$ then $u$ is a constant function.
Based on a joint work (in progress) with L. Buhovsky, Eu. Malinnikova, and M. Sodin.
Svitlana Mayboroda (University of Minnesota): The hidden landscape of localization of eigenfunctions
Numerous manifestations of wave localization permeate acoustics, quantum physics, mechanical and energy engineering. It was used in construction of noise abatement walls, LEDs, optical devices, to mention just a few applications. Yet, no systematic methods could predict the exact spatial location and frequencies of the localized waves.
In this talk I will present recent results revealing a new criterion of localization, tuned to the aforementioned questions, and will illustrate our findings in the context of the boundary problems for the Laplacian and bilaplacian, $div A\nabla$, and (continuous) Anderson and AndersonBernoulli models on a bounded domain. Via a new notion of "landscape" we connect localization to a certain multiphase free boundary problem and identify location, shapes, and energies of localized eigenmodes. The landscape further provides estimates on the rate of decay of eigenfunctions and delivers accurate bounds for the corresponding eigenvalues, in the range where both classical Agmon estimates and Weyl law may fail.
Wilhelm Schlag (University of Chicago): Long term dynamics of nonlinear wave equations
We will review some of the work over the past decade aiming at a complete description of the asymptotic structure of solutions with finite energy to certain semilinear wave equations. A goal of this talk is to demonstrate the interplay between dynamical system ideas and methods (invariant manifolds in infinite dimensions), calculus of variations, and the solution theory of dispersive equations based on classical harmonic analysis (restriction theory of the Fourier transform and Strichartz estimates). We will also present new work on a damped wave equation, but with damping that vanishes asymptotically. The latter is joint work with Nicolas Burq and Genevieve Raugel at Orsay, France.
Friday: Complex/Real/Harmonic Analysis
Mario Bonk (UCLA): Quasisymmetric rigidity for Sierpinki carpets
Sierpinski carpets exhibit surprising rigidity under quasisymmetric maps. This phenomenon appears in various contexts in geometric group theory and complex dynamics. In my talk I will give a survey of some recent results in this area.
Lesley Ward (University of South Australia): Product Hardy spaces associated to operators with heat kernel bounds on spaces of homogeneous type
Much effort has been devoted to generalizing the CalderónZygmund theory from Euclidean spaces to metric measure spaces, or spaces of homogeneous type. Here the underlying space $\mathbb{R}^n$ with Euclidean metric and Lebesgue measure is replaced by a set $X$ with a general metric or quasimetric and a doubling measure. Further, one can replace the Laplacian operator that underpins the CalderónZygmund theory by more general operators $L$ satisfying heat kernel estimates. I will present recent joint work with P. Chen, X.T. Duong, J. Li and L.X. Yan along these lines. We develop the theory of product Hardy spaces $H^p_{L_1,L_2}(X_1 \times X_2)$, for $1\leq p <\infty$, defined on products of spaces of homogeneous type, and associated to operators $L_1$, $L_2$ satisfying DaviesGaffney estimates. This theory includes definitions of Hardy spaces via appropriate square functions, an atomic Hardy space, a CalderónZygmund decomposition, interpolation theorems, and the boundedness of a class of Marcinkiewicztype spectral multiplier operators.
Alex Poltoratski (Texas A&M University): Spectral gaps and the size of uncertainty
I will talk about a recent solution to the socalled gap problem in Fourier analysis and its applications in complex analysis and spectral theory for differential operators.
Luke Rogers (University of Connecticut): Settings in which many Sobolev spaces are not algebras
Let $(X,\mu)$ be a measure space on which there is a nonnegative definite selfadjoint Markovian operator $\mathcal{L}$ with dense domain in $L^2(\mu)$. The cannonical example is the (nonnegative) Laplacian on Euclidean space, and in other contexts it is known that natural examples of such operators $\mathcal{L}$ can be used in place of the Laplacian to define differential equations for physical phenomena such as wave and heat propagation on the space $X$. The corresponding Sobolev spaces are $W^{\alpha,p}_{\mathcal{L}}=\{ f\in L^p: \mathcal{L}^{\alpha/2}\in L^p\}$.
In the Euclidean setting with $\mathcal{L}=\Delta$ it is wellknown that the space $W^{\alpha,p}_{\Delta}\cap L^\infty$ is an algebra when $p\in(1,\infty)$ and $\alpha > 0$. There are extensions of this result to Lie groups with polynomial volume growth and manifolds with positive injectivity radius and nonnegative Ricci curvature. In joint work with Thierry Coulhon we give bounds on the range of $p$ and $\alpha$ for which such results can be true in a general space $(X,\mu)$ by exhibiting a class of fractal spaces and operators for which the algebra property fails.
Paul F. X. Müller (J. Kepler Universität Linz): Davis and Garsia inequalities for Hardy martingales in Banach spaces
We present Davis decompositions for Hardy martingales with values in Banach spaces and use them to derive Davis and Garsia inequalities for vector valued Hardy martingales. We relate the underlying isomorphic invariants to the concept of $H^1$ uniform convexity.
Xavier Tolsa (ICREA  U. Autonoma de Barcelona): Harmonic measure, Riesz transforms, and uniform rectifiability
In this talk I will review some recent results on harmonic measure where the connection between Riesz transforms and rectifiability plays an essential role. In particular, I will recall a converse of the Riesz brothers theorem and the solution of the socalled two phase problem. I will also explain a more recent result on a characterization of uniform rectifiability in terms of Carleson estimates for bounded harmonic functions which is based on a corona decomposition involving harmonic measure. Some of these results are collaborations with J. Azzam, J. Garnett and M. Mourgoglou.
