Perspectives in Real Geometry
September 18 – 22, 2017

Scientific Committee

Michel Coste (Université de Rennes 1)
Elisha Falbel (Université Pierre et Marie Curie)
Viatcheslav Kharlamov (Université de Strasbourg)
Janos Kollar (Princeton University)

Organizing Committee

Erwan Brugallé (Université de Nantes)
Ilia Itenberg (Université Pierre et Marie Curie)
Eugenii Shustin (Tel Aviv University)

The main topic of the workshop is modern real algebraic geometry with an emphasis on the interactions with neighboring domains, such as low-dimensional topology, complex algebraic geometry, symplectic geometry and enumerative geometry.

The workshop is dedicated to the memory of Jean-Jacques Risler.
