The Valley Geometry Seminar meets Friday afternoons in 1634 LGRT at the University of Massachusetts. It is a five-college seminar (Amherst College, Hampshire College, Mount Holyoke College, Smith College and the University of Massachusetts). The seminar generally is 4:00-5:00 PM with refreshments at 3:45.

The topics include geometry in all its various forms (algebraic and differential geometry, geometric representation theory, topology, combinatorics, symbolic computation, commutative algebra, applications to and from physics, etc.) as well as other topics. The talks are intended for a general audience with geometric interests of some form or other.
