The singular values of compact pseudodifferential operators with spatially nonsmooth symbols
A. I. Karol' St. Petersburg State University, Mathematics and Mechanics Faculty
Abstract:
Considering compact pseudodifferential operators with symbols whose smoothness in $x$ vanishes on a prescribed set, we obtain some validity conditions for the Weyl spectral asymptotics of singular values. These results are applied to the symbols whose decay order as $|\xi| \to \infty$ is a nonsmooth function of $x$.
Keywords:
pseudodifferential operator, nonsmooth symbol, singular values, Weyl's asymptotics.
