New cases of logarithmic equivalence of Welschinger and Gromov-Witten invariants

Ilia Itenberg, Viatcheslav Kharlamov, Eugenii Shustin

Published 2006-12-27Version 1

We consider the product of two projective lines equipped with the complex conjugation transforming $(x,y)$ into $(\bar{y},\bar{x})$ and blown up in at most two real, or two complex conjugate, points. For these four surfaces we prove the logarithmic equivalence of Welschinger and Gromov-Witten invariants.
