A Lagrangian Klein bottle you can't squeeze

Abstract: Given a nonorientable Lagrangian surface L in a symplectic 4-manifold, how far can you deform the symplectic form before there is no Lagrangian surface isotopic to L? I will discuss this problem in general and explain the solution in a particular case.
