On the propagation of isotropic Sobolev singularities

The aim of this talk is to recall the basics of isotropic pseudodifferential calculus and, consequently, to examine the propagation of isotropic Sobolev (micro)singularities for an evolution problem whose generator is given by the Weyl quantization of a complex quadratic form on phase space. This talk is based on joint work with Marcello Malagutti and Alberto Parmeggiani.
