An introduction to computing modular forms using modular symbols
In this survey paper, we explain how weight-two modular
forms on Gamma0(N) are related to modular symbols, and how to use
this to explicitly compute spaces of modular forms.
I also gave a talk on this material, which resulted in
some fun slides.
- msri-intro.pdf is a PDF version
of the paper.
- msri-intro.tgz contains everything you
need to build the paper (the latex file and the diagrams).
