Zworski (UC Berkeley) examines the relationships between dynamical systems and the behavior of solutions to various partial differential equations and pseudodifferential equations containing a small positive parameter h. The graduate textbook introduces the Fourier transform of smooth functions, Wehl quantization, semiclassical defect measures, a semiclassical version of Beal's theorem, a new class of Kohn-Nirenberg symbols, phase functions for Fourier integral operators, Egorov's theorem, microlocal normal forms, and pseudo differential operators on manifolds.
