Middle-dimensional symplectic rigidity. 
Abstract: In this talk I will discuss a middle dimensional generalization of Gromov's nonsqueezing theorem. I will explain how Viterbo's capacities can be used to find middle-dimensional rigidity for the image of coisotropic cylinders by certain types of Hamiltonian diffeomorphisms. Moreover, we will see that this type of rigidity also appears in infinite-dimensional settings associated to certain types of Hamiltonian PDEs. As a particular example this result can be applied to the Sine-Gordon equation.
