Title:The Inverse Galois Problem for PSL_2(F_p)
Seminar:Job Candidate Talk
Speaker:David Zywina
Abstract Link:http://
Abstract:
The Inverse Galois Problem asks whether every finite group occurs as the Galois group of some extension of the rationals. This problem is still wide open, even in the special case of simple groups. In this talk, we will explain why each of the simple groups PSL_2(F_p) occurs as a Galois group; these are the "simplest" simple groups for which the Inverse Galois Problem was not completely settled. Our Galois extensions will arise by studying the cohomology of a well-chosen surface. An important role will also be played by the L-functions of certain elliptic curves.
