Title:
Cross ratios and Surface groups.

Abstract of Talk

I will recall the classical construction of the projective cross ratio of four lines and the so-called fundamental theorem of projective geometry. Then I will explain that the formal properties of the cross ratio can be abstracted and use to describe "geometries" on surfaces. I will spend most time about Teichmüller Theory.
