Explicit Bases of Modular Symbols over Function Fields
Cécile Armana (University of Franche-Comté)
Abstract:
Modular symbols are an important tool for computing modular forms. In this talk I will discuss a theory of modular symbols over the function field of positive characteristic
, which provides a way of computing certain automorphic forms over
and Drinfeld modular forms. I will focus on a finite presentation for the space of such symbols, and explain how it can be solved in a explicit way.
