Abstract

Sobolev wavefront sets and 22-microlocal spaces play a key role in describing and analyzing the singularities of distributions in microlocal analysis and solutions of partial differential equations. Employing the continuous shearlet transform to Sobolev spaces, in this paper we characterize the microlocal Sobolev wavefront sets, the 22-microlocal spaces, and local H\"older spaces of distributions/functions. We then establish the connections among Sobolev wavefront sets, 22-microlocal spaces, and local H\"older spaces through the continuous shearlet transform.
