DESCRIPTION:The talk is devoted to several real and tropical enumerative p
 roblems. We suggest new invariants of the projective plane (and\, more ge
 nerally\, of certain toric surfaces) that arise from appropriate signed e
 numeration of real algebraic curves of genus 1 and 2.These invariants adm
 it a refinement (according to the quantum index) similar to the one intro
 duced by Grigory Mikhalkin in the genus zero case. It turns out that two 
 different rules of signs in the enumeration surprisingly lead to the same
  collection of refined invariants.The proof of the latter fact uses the t
 ropical counterparts of the invariants under consideration.This is a join
 t work with Eugenii Shustin.
