The Algebra and Topology seminar invites speakers from a broad spectrum of areas, including algebraic and differential geometry, algebraic topology, low-dimensional topology, representation theory, quantum algebra, and number theory.

There is also a Google calendar for the seminar, which typically lists scheduled speakers in advance of their posting here.
