Propagation of Shubin-Sobolev singularities of Weyl-quantizations of complex quadratic forms
Marcello Malagutti, Alberto Parmeggiani, Davide Tramontana
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 evoluti…

Smoothing effect for third order operators with variable coefficients
Serena Federico, Davide Tramontana
In this work we study the smoothing effect of some variable coefficient operators of the form , where is a Weyl-quantized pseudo-differential operator of order .…
