Characterisation of Two-Microlocal Spaces and Wavefront Sets by Wavelet Transforms and Their Application to Solutions of Schrödinger Equations
摘要
In this paper, we characterise Hölder continuity, two-microlocal spaces, and the Sobolev wavefront set, and propose a novel representation of the solutions of Schrödinger equations for a free particle using the wavelet transform introduced by Moritoh in Moritoh (Tohoku Math J 47:555–565, 1995). Additionally, we discuss its application in determining the microlocally regular solutions to the Schrödinger equations of a free particle, providing a refined understanding of their microlocal regularity properties.
