Propagation of singularities for anharmonic Schr\"odinger equations

Analysis of PDEs 2025-03-05 v2 Functional Analysis

Abstract

We consider evolution equations for two classes of generalized anharmonic oscillators and the associated initial value problem in the space of tempered distributions. We prove that the Cauchy problem is well posed in anisotropic Shubin--Sobolev modulation spaces of Hilbert type, and we investigate propagation of suitable notions of singularities.
