DESCRIPTION:Speakers: Abdelouahab Khelifati (IMT)\n\nRiemann surfaces are 
 geometric shapes that can be imagined as deformed spheres or doughnuts. At
  first sight they may look quite similar\, but a simple topological featur
 e -the number of "holes'' they have- turns out to have a remarkable influe
 nce on their geometry.In this talk\, we explore how the topology of a Riem
 ann surface shapes the behavior of complex curves drawn on it. While some 
 surfaces happily accommodate many curves\, others behave quite differently
 : their geometry seems to push curves away !The goal of this talk is to gi
 ve an intuitive glimpse of this phenomenon and to show how the simple act 
 of adding holes to a surface can dramatically change the geometric world t
 hat lives on it. Through pictures and geometric intuition\, we will see ho
 w topology quietly governs the shapes and curves that a surface allows.\n\
