Gohberg Lemma and Spectral Results for Pseudodifferential Operators on Locally Compact Abelian Groups

Néstor Jara, Marius Măntoiu

We provide a new type of proof for known or new Gohberg lemmas for pseudodifferential operators on Abelian locally compact groups $\mathrm{X}$. We use $C^{\ast }$-algebraic techniques, w…
