Algebraic Geometry / Commutative Algebra Seminar
The working AG/CA seminar will be devoted to syzygies of curves.
We will try to make everything accessible to graduate students
who take the class in algebraic geometry.
So essentially this will be one long exercise on applying basic tools of Algebraic Geometry.
This will dictate the choice of material but the hope (probably too optimistic)
is to understand at least the most basic ideas and insights
behind the recent proof of Green's Conjecture by Claire Voisin.
As usual, everybody is wellcome to contribute talks.
