Méthodes opératorielles. Traduit du russe par Djilali Embarek. (English) Zbl 0651.47039

Moscou: Éditions Mir. 707 p. (1987).
In this graduate text the author develops a new operational calculus: the calculus of ordered non-commutative operators, and proves the fundamental theorem of quasi-inversion for such operators. New algebraic and geometric notions tie together differential equations, spectral theory and symplectic geometry. The contents is as follows: introduction to operational calculus, abstract spaces, functional spaces, functions of regular operators, non-commutative operator calculus, T-product of hypoelliptic operators and spectral decomposition of a T-product, generalized Hamilton-Jacobi equation, canonical operator on a Lagrangean manifold with complex germs and proof of the fundamental theorem, and theory of linear equations on semi-modules.
The clear presentation is the result of three years of teaching on this subject by the author before 1973. One can find a relevant bibliography in a more recent work by the author and V. E. Nazaikinskii [Asimptoticheskie metody resheniya psevdodifferentsial’nykh uravnenii; English: Asymptotics of Operator and Pseudo-Differential Equations, Consultant Bureau, New York and London, 1988]. The reviewed book appeared in English [Operational Methods (1973; Zbl 0449.47002)] and in Spanish [Métodos operatorios (1981; Zbl 0528.47034)], the original is in Russian (1973; Zbl 0288.47042).
