Title: Tropical enumerative geometry
Abstract: Over the last 7 years the tropical algebraic geometry provided a number of spectacular applications to the theory of Gromov-Witten and Welschinger invariants. In the talk, we will present the main elements of the tropical enumerative geometry, tropical curves and their moduli spaces, tropical intersection theory, tropical enumerative invariants, and we will show that the tropical enumerative geometry serves not only as a technical computational tool, but gives new insights to the algebraic enumerative geometry. A special attention will be paid to the real algebraic and tropical enumerative invariants.
