Propagation of Shubin-Sobolev singularities of Weyl-quantizations of complex quadratic forms
arXiv:2503.20955
Abstract
The aim of this work is to develop the Hörmander microlocal theory in the isotropic framework and use the results we obtain to study the propagation of singularities for an evolution problem, with diffusive part given by a Weyl-quantization of a complex quadratic form on the phase space.
