DESCRIPTION:Abstract:\n\n	Hypergeometric local systems that carry a ration
 al variation of Hodge structure are known to come from geometry. There are
  natural candidates for where they come from\, the so-called canonical mod
 els\, but their dimension is usually larger than the weight of the variati
 on. In this talk I will look at the simplest interesting case\, Hodge numb
 ers (1\,1)\, and explain how the canonical models can be cut down to ellip
 tic surfaces. I’ll also describe all the integral structures sitting ins
 ide the rational variation and show where each one comes from geometricall
 y. This is joint work in progress with Martin Mereb and Fernando Rodriguez
  Villegas.\n\n//indico.ictp.it/event/11568/
