Speaker: Fran├žois Seguin

Title: Towards positive density of quartic polynomials yielding extensions of class number one

Abstract: Given a polynomial over a finite field, we can define a quadratic extension of the function field $F_q(t)$, and ask how often those have class number one. During this talk, we will focus on the case where the polynomials are of degree 4, present some previous results about this question, and outline an unpublished proof by R. Murty and R. Gupta suggesting positive density of such polynomials.


Thursday, June 15, 1:30 p.m. Jeffery 422 - Curves Seminar

Speaker: Mike Roth

Title: Examples IV

Abstract: We will finish the example of d points in P^1, up to projective automorphisms.
