Systems of Microdifferential Equations (Progress in Mathematics) - Tapa dura

This volume is based on notes from a graduate course given by the author at the University of Paris. The text has been translated into English, and a preface which facilitates access to the notes has been written by Jean-Luc Brykinski of Brown University and the Ecole Polytechnique. The field of microdifferential equations, to which the author has made substantial contributions, is an active area of mathematical research with applications to real and complex analysis, Lie groups, algebraic geometry, the topology of algebraic varieties, and mathematical physics (Feynman amplitudes). The volume will be of interest to graduate students and research mathematicians alike.
