Complex Algebraic Geometry

Multiplier Ideals and Singularities
1:00pm|S-101

The method of multiplier ideals is one of the most versatile tools to study singularities of varieties. For the local theory, we present a connection between multiplier ideals and D-modules based on joint work with M. Mustata and M. Saito which has...

Computer Science/Discrete Mathematics Seminar II

An Invitation to Combinatorial Games
10:30am|S-101

Combinatorial game theory is the study of combinations of two-player games with no hidden information and no chance elements. The subject has its roots in recreational mathematics, but in its modern form involves a rich interplay of ideas borrowed...

Computer Science/Discrete Mathematics Seminar I

Randomness-Efficient Sampling Within NC^1
Alex Healy
11:15am|S-101

It is now well-known that a random walk on an expander graph is a very good "sampler", and this has been used to prove a variety of important results in complexity theory, cryptography and algorithms. On the surface, however, taking a walk on an...

Fundamental Lemma

Symmetry of the Hitchin Fibration
10:30am|S-101

I will describe the construction the symmetries of the Hitchin fibration and the way in which the endoscopic groups appear in the variation of these symmetry groups.
