Higher genus Welschinger invariants under real surgeries
Ding, Yanqiao
Original · EN
According to [3], a real surgery of a real del Pezzo surface Xᵣ along a real sphere S is a modification of the real structure on Xᵣ in a neighborhood of S. In this paper, we study the behavior of higher genus Welschinger invariants under real surgeries, and obtain a genus decreasing formula of Welschinger invariants.
