dc.description.abstract
Let (S2,w) be a symplectic sphere, and let 𝜏�:S2→S2 be an anti‐symplectic involution of (S2,w). We consider the product (S2,w)×(S2,w) endowed with the anti‐symplectic involution 𝜏�x𝜏�, and study the space of monotone anti‐invariant symplectic forms on this four‐manifold. We show that this space is disconnected. In addition, during the course of the proof, we produce a diffeomorphism of Gr(2,4) which induces the identity map on all homology and homotopy groups, but which is not homotopic to the identity.
