DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OBAGS/1/">Re
 al enumerative invariants and their refinement</a>\nby Ilia Itenberg (imj-
 prg) as part of ODTU-Bilkent Algebraic Geometry Seminars\n\n\nAbstract\nTh
 e talk is devoted to several real and tropical enumerative problems. We su
 ggest new invariants of the projective plane (and\, more generally\, of to
 ric surfaces) that arise as results of an appropriate enumeration of real 
 elliptic curves.\nThese invariants admit a refinement (according to the qu
 antum index) similar to the one introduced by Grigory Mikhalkin in the rat
 ional case. We discuss tropical counterparts of the elliptic invariants un
 der consideration and establish a tropical algorithm allowing one to compu
 te them.\nThis is a joint work with Eugenii Shustin.\n
