TITLE: Q(sqrt(5)) is the new Q SPEAKER: William Stein (UW) ABSTRACT: I will talk further about elliptic curves and modular forms over Q(sqrt(5)). I will do some of the following: (1) give an example, (2) say something about the analogue of modular curves over Q(sqrt(5)), (3) say more about what is involved in an algorithm to compute modular forms over Q(sqrt(5)). The main prerequisite for this talk will be "algebraic number theory".
