A taste of convex geometry

In this talk we would like present a taste of convex geometry starting with classical ideas of Brunn and Minkowski then passing through modern idea of concentration of measure and time permits wrapping up with Dvoretzky's Theorem. This is joint work with B.Ergur and D.Espresso.

A 4-manifold with no real projective structure

Cooper and Goldman proved that the connected sum of two copies of real projective 3-space does not admit a real projective structure. This is the first known example of a connected 3-manifold without a real projective structure. In this talk, we will give an introduction of projective structures and show that the connected sum of two copies of real projective 4-space does not admit a real projective structure.
