Computational Algebra Seminar: Assaf -- Decomposition of Jacobians of modular curves

Time & Place: 15:00 -- 16:00, Thursday 6 February, SMRI Seminar Room
Name: Eran Assaf (MIT)
Title: Decomposition of Jacobians of modular curves
Abstract:
In the talk, I will present an efficient algorithm to compute the decomposition
of the Jacobians of modular curves of arbitrary level, using modular symbols.
This is obtained by working intrinsically with the curve, unlike previous
methods. I will also discuss the possible consequences for deriving equations
of modular curves.
