,Empirical Sources (1990–1997),l operators a symbolic calculus for pseudodifferential operators on . (modulo operators acting from .(.) to .(.) for arbitrary .). Similar questions are considered for pseudodifferential operators with ‘periodic’ (in the sense of §7, Chapter 3) symbols.

Introduction,d instrument in various branches of mathematics, such as mathematical physics, functional analysis, and topology. Several monographs have been devoted to this theory ([40], [67], [68], [69], [73], [74], etc.); in them pseudodifferential operators arise in the ‘smooth’ case — with smooth symbols (coe

The spectrum of a ,* -algebra of pseudodifferential operators with discontinuous symbols on a closebra . generated by the pseudodifferential operators with smooth symbols on a smooth closed manifold . becomes commutative after factorization by the ideal .(.) of compact operators. Hence all irreducible representations of the quotient algebra ./.(.) are one-dimensional, and its spectrum can be iden
