## Infinitely many non-isotopic real symplectic forms on the quadric surface

##### Abstract:

A real symplectic manifold is a symplectic manifold endowed with an involution which is anti-symplectic. Given a real symplectic manifold, we may ask: are there any anti-invariant symplectic forms which are cohomologous but not isotopic within anti-invariant forms? In this talk, we will show that such disconnectivity indeed appears for certain real quadric surfaces.
