+**“Affine Real Cubic Surfaces”**
-  Ilia Itenberg (Sorbonne)
+Abstract: (A joint work with V.Kharlamov) We prove that the space of
-  Real enumerative invariants and their refinement
+affine, transversal at infinity, non-singular real cubic surfaces has 15 connected components. We give a topological criterion to distinguish them and show also how these 15 components are adjacent to each other via wall-crossing.
-  Salle 6-13, 14h15
-**Abstract:**
+[[fables| seminar page]]
-The talk is devoted to several real and tropical enumerative problems.
-We suggest new invariants of the projective plane (and, more generally, of toric surfaces)
-that arise as results of an appropriate enumeration of real elliptic curves.
-These invariants admit a refinement (according to the quantum index) similar to the one introduced by Grigory Mikhalkin in the rational case.
-We discuss the combinatorics of tropical counterparts of the elliptic invariants under consideration and establish a tropical algorithm
-allowing one to compute them.
-This is a joint work with Eugenii Shustin.
