Date: Thursday 1st December 2011 <br />Speaker: Joan Simon (Edinburgh). <br />Title: Topology from cosmology. <br /> <br />Abstract : I will informally discuss how the Euler number of Calabi-Yau 3-folds (CY) can be constrained due to cosmological inflationary measurements in certain string theory compactification set-ups. The emphasis of the talk will be on the links between seemingly different disciplines rather than in a precise theoretical presentation. <br /> <br />http://www.maths.ed.ac.uk/cheltsov/seminar/
