Valley Geometry Seminar

The Valley Geometry Seminar meets Friday afternoons in LGRT 1681 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 is generally 4:00-5:00 PM.

The talks are intended for faculty and graduate students with geometric interests of some form or other: algebraic geometry, differential geometry, modern homotopy theory, geometric representation theory, topology, geometric combinatorics, commutative algebra, applications to and from physics, etc.

The webpage is maintained by the robot. Human inquiries should be directed to Paul Hacking (email: hacking@umass.edu), Jessica Sidman (email: jsidman@amherst.edu), or Jenia Tevelev (email: tevelev@umass.edu).
