Название: Microlocal analysis for differential operators: An introduction
Авторы: Grigis A., Sjostrand J.
This short introduction to microlocal analysis is presented, in the spirit of H?rmander, in the classical framework of partial differential equations. This theory has important applications in areas such as harmonic and complex analysis, and also in theoretical physics. Here Grigis and Sj?strand emphasize the basic tools, especially the method of stationary phase, and they discuss wavefront sets, elliptic operators, local symplectic geometry, and WKB-constructions.
