This page is maintained by Michael Thaddeus and was shamelessly, indirectly copied from Pasha Belorousski.

Other, equally shameless thefts: the Harvard/MIT Algebraic Geometry Seminar, the Stanford Algebraic Geometry Seminar, the Brown University Geometry Seminar, the Geometry, Representation theory, and Moduli Seminar at Princeton, the UIC Algebraic Geometry Seminar, the Utah Algebraic Geometry Seminar, the Toronto Number Theory/Representation Theory Seminar, the Arithmetic, Combinatorics, and Topology Seminars at the University of Michigan, the Seminar on Topics in Arithmetic Geometry, Etc. at MIT, and the Algebraic Geometry and Differential Topology Seminar at the Rényi Institute in Budapest. Also note the suspiciously colored background of the Queen's Algebraic Geometry Seminar.
