|JOINT ARITHMETIC HOMOGENEOUS SPACES AND NUMBER THEORY|
|Topic:||Some Modular Generating Functions for Arithmetic Cycles|
|Date:||Friday, March 31|
|Time/Room:||11:00am - 12:00pm/S-101|
In this talk I will give an overview of joint work with M. Rapoport and T. Yang on the construction of generating series whose coefficients are the classes of special divisors and 0-cycles on the arithmetic surfaces attached to Shimura curves. These series are the q-expansions of modular forms of genus 1 and 2 respectively. I will then describe an arithmetic inner product formula and an arithmetic Siegel-Weil formula involving these forms. If time permits at the end, I will discuss some open problems.
