Title:The geometry of etale fundamental groups of curves over Q_p^{un}
Seminar:Algebra and Number Theory Seminar
Speaker:Hilaf Hasson, Penn State University
Abstract:
I will begin with a quick survey about the field of moduli of Galois branched covers of the projective line, and the utility of this notion towards solving the Inverse Galois Problem. I will proceed to describe the Galois action of Q_p^{un} on the prime-to-p geometric fundamental group of the projective line minus a few points. This and other theorems will be discussed in the context of improving descent results about Galois branched covers of the projective line over various fields.
