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on the case where the polynomials are of degree 4, present some previous results about this question, and outline an unpublished proof by R. Murty and R. Gupta suggesting positive density of such polynomials.

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