Relative open Gromov-Witten invariants


Abstract
             

The modern framework of the complex enumerative geometry is the Gromov-Witten theory. The real enumerative geometry has its subtleties, but thanks to Welschinger, and more recently to Solomon, they were overcome and nowadays there exist "open Gromov-Witten" invariants responsible for counting real rational curves. In this talk, I will present a recent joint work with Jake Solomon in which we introduce invariants responsible for counting real rational curves subject to tangency conditions.
