Semigroups for quadratic evolution equations acting on Shubin-Sobolev and Gelfand-Shilov spaces
Patrik Wahlberg
We consider the initial value Cauchy problem for a class of evolution equations whose Hamiltonian is the Weyl quantization of a homogeneous quadratic form with non-negative definit…

The Gabor wave front set of compactly supported distributions
Patrik Wahlberg
We show that the Gabor wave front set of a compactly supported distribution equals zero times the projection on the second variable of the classical wave front set.
