Advances in Phase Space Analysis of Partial Differential Equations

This collection of original articles and surveys addresses the recent advances in linear and nonlinear aspects of the theory of partial differential equations. The key topics include operators as "sums of squares" of real and complex vector fields, nonlinear evolution equations, local solvability, and hyperbolic questions.

Provides both surveys and recent advances in phase space analysis for pdes Distinguished mathematicians address current work of importance Includes supplementary material: sn.pub/extras
