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…

On The Spectral Zeta Function Of Second Order Semiregular Non-Commutative Harmonic Oscillators
Marcello Malagutti
In this paper we give a meromorphic continuation of the spectral zeta function for semiregular Non-Commutative Harmonic Oscillators (NCHO). By ``semiregular system'' we mean system…
