Singularity for Solutions of Linearized KdV Equations

Keiichi Kato, Masaki Kawamoto, Koichiro Nanbu

We investigate the time propagation of singularity of a solution to linearized KdV equation by using the characterization of wave front sets with using to the wave packet transform…

Wave front set of solutions to Schrödinger equations with perturbed harmonic oscillators

Keiichi Kato, Shingo Ito

In this paper, we determine the wave front sets of solutions to Schrödinger equations of a harmonic oscillator with sub-quadratic perturbation by using the representation of the Sc…
