DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AGNES/12/">T
 he moduli space of rational elliptic surfaces of index two</a>\nby Aline Z
 anardini (Leiden) as part of Algebraic Geometry NorthEastern Series (AGNES
 )\n\n\nAbstract\nElliptic surfaces are ubiquitous in Mathematics. Examples
  include Enriques surfaces\, Dolgachev surfaces\, and all surfaces of Koda
 ira dimension one. In this talk we will focus on those elliptic surfaces w
 hich are rational and that have exactly one multiple fiber of multiplicity
  two. These are called rational elliptic surfaces of index two. Our goal w
 ill be to describe how to construct their moduli space when the choice of 
 a bisection is part of the classification problem. This is based on work i
 n progress joint with Rick Miranda.\n
