DESCRIPTION:Aline Zanardini (University of Leiden)\nElliptic surfaces are 
 ubiquitous in Mathematics. Examples include Enriques surfaces\, Dolgachev 
 surfaces\, and all surfaces of Kodaira dimension one. In this talk we will
  focus on those elliptic surfaces which are rational and that have exactly
  one multiple fiber of multiplicity two. These are called rational ellipti
 c surfaces of index two. Our goal will be to describe how to construct the
 ir moduli space when the choice of a bisection is part of the classificati
 on problem. This is based on work in progress joint with Rick Miranda.
