Non‐harmonic Gohberg's lemma, Gershgorin theory and heat equation on manifolds with boundary
Abstract We use Operator Ideals Theory and Gershgorin theory to obtain explicit information in terms of the symbol concerning the spectrum of pseudo‐differential operators, on a smooth manifold Ω with boundary , in the context of the non‐harmonic analysis of boundary value problems introduced in [29] in terms of a …
