We study the lagrangian embedding as a fixed point set of anti-symplectic involution r on a symplectic 4-manifold X. Suppose the fixed loci of τ are the disjoint union of smooth Riemann surfaces X τ = UΣ i ; then each component becomes a lagrangian submanifold. Furthermore, if one of the components is a Riemann surface of genus g > 2, then its quotient has vanishing Seiberg-Witten invariants. We will discuss some examples which allow an anti-symplectic involution with lagrangian fixed loci.
