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.47 pages, 6 figures; recursive formulas corrected (missing terms added)Algebraic Geometry14N10 (Primary) 14P05; 14N35; 51N35 (Secondary)A Caporaso-Harris type formula for Welschinger invariants of real toric Del Pezzo surfacestext
