Developed a theory of ultradifferentiable sheafs with applications.
Chevalley theorems extended to isotropic functions on matrix spaces.
A systematic geometric theory for the ultradifferentiable (non-quasianalytic and quasianalytic) wavefront set similar to the well-known theory in the classic smooth and analytic setting is developed. In particular an analogue of Bony's Theorem and the invariance of the ultradifferentiable wavefront set under diffeomorp…
Uniform proof for ultradifferentiability in various classes and dimensions.
The paper extends properties of smooth functions to closed sets and maps.
