Towards relative invariants of real symplectic 4-manifolds

Jean-Yves Welschinger

Let $(X, ω, c_{X})$ be a real symplectic 4-manifold with real part $R X$ . Let $L \subset R X$ be a smooth curve such that $[L] = 0 \in H_{1} (R X; Z /2 Z)$ . We construct invariants un…

Invariants of real symplectic 4-manifolds out of reducible and cuspidal curves

Jean-Yves Welschinger

We construct invariants under deformation of real symplectic 4-manifolds. These invariants are obtained by counting three different kinds of real rational J-holomorphic curves whic…
