Algebra and Topology Seminar

These seminars invite 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.

Complements in syntactic semialgebraic geometry - for Amnon Neeman, on the occasion of his travels to Europe, the Americas, and possibly other foreign lands

In this talk, I’ll explain how “complements of presheaves” give solutions (or probable solutions!) to these questions. In particular, I’ll give an example (the first!) of a nontrivial finite etale extension of “genuine” semirings.
