In mathematics, a '''microdiiferential operator''' is a linear operator on a cotangent bundle (phase space) that generalizes a [[differential operator]] and appears in the framework of [[microlocal analysis]] as well as in the Kyoto school of [[algebraic analysis]]. The notion was originally introduced by L. Boutet de Monvel and P. Krée.
