+  Real enumerative invariants and their refinement
+  Salle 6-13, 14h15
+**Abstract:**
+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.
