University of North Carolina at Chapel Hill
Geometric Methods in Representation Theory Seminar

Fridays 4pm, PH-367

The aim of this seminar is to bring speakers from this area and outside to speak on topics related to Representation Theory (specially geometric and topological methods employed in Representation Theory). The speakers are expected to give their talks at a level suitable for graduate students.
