Wave front set of solutions to Schrödinger equations with perturbed harmonic oscillators (1908.08358v2)
Published 22 Aug 2019 in math.AP
Abstract: In this paper, we determine the wave front sets of solutions to Schr\"odinger equations of a harmonic oscillator with sub-quadratic perturbation by using the representation of the Schr\"odinger evolution operator of a harmonic oscillator via the wave packet transform.
