Representation Theory and Geometry of Symplectic Resolutions**

Date: May 18, 2015 - May 21, 2015

Location: Northeastern University, Boston

URL: http://math.mit.edu/conferences/symplectic-resolutions/index.php

Description:

The conference will concentrate on the representation theoretic and geometric
