Upcoming seminars March 7 (Thu), 2024, 16:00--17:00, Room 8101 Title: Representation numbers of Bell-type quadratic forms Speaker: Yeongwook Kwon (UNIST) Abstract: In 1834, Jacobi proved his four-square theorem. The sum of four squares can be viewed as an example of the so-called Bell-type quadratic forms, and the representation number of Bell-type quadratic forms were studied by several authors. However, most preceding results only dealt with Bell-type forms of class number 1. In this talk, we derive a closed formula for the representation numbers of each Bell-type quadratic form of class number less than or equal to 2. This is joint work with Chang Heon Kim, Kyoungmin Kim and Soonhak Kwon. |
