Semi-Classical Wavefront Set and Fourier Integral Operators
arXiv:math/0407460
Abstract
We define and prove some properties of the semi-classical wavefront set. We also define and study semi-classical Fourier integral operators, of which we give a complete characterization. Lastly, we prove a generalization of the semi-classical Egorov's Theorem to manifolds of unequal dimensions.
