Resumen de A Caporaso-Harris type formula for Welschinger invariants of real toric Del Pezzo surfaces

Ilia Itenberg , Viatcheslav Kharlamov, Eugenii Shustin

• We define a series of relative tropical Welschinger-type invariants of real toric surfaces. In the Del Pezzo case, these invariants can be seen as real tropical analogs of relative Gromov�Witten invariants, and are subject to a recursive formula. As application we obtain new formulas for Welschinger invariants of real toric Del Pezzo surfaces.
