# Modular Forms¶

This section is about computing with modular forms, modular symbols, and modular abelian varieties. Most of the Sage functionality we describe below is new code written for Sage by myself, Craig Citro, Robert Bradshaw, and Jordi Quer in consultation with John Cremona. It has much overlap in functionality with the modular forms code in Magma, which I developed during 1998-2004.
