3:45PM: Felix Klein, Galois Theory, and the Icosahedron

Jeremy Gray

Why do we have the version of Galois theory that we do -- why, indeed, do we have Galois theory at all? This talk traces conflicting 19th-century visions of what it would be to solve, or better to understand, polynomial equations and finds the forgotten role of Felix Klein in promoting Galois's ideas in Germany and America.

5:00PM: Indecomposable rank two bundles on Pn

Mengyuan Zhang

This is a background talk on problems about indecomposable rank two bundles on Pn. We pay special attention to those that are limits of split bundles.
