Moskva: ”Nauka” Glavnaya Redaktsiya Fiziko-Matematicheskoj Literatury. 240 p. R. 2.20 (1982).

The book is dedicated to a modern part of science, the study of convolution equations in a complex as well as in a real space. Approximation results for the solution of homogeneous convolution equations by elementary solutions are given. Basic is the decomposition theorem and the uniqueness theorem for hyperfunctions.

The approximation theorem is proved for convolution equations in tube domains, for systems of homogeneous convolution equations and homogeneous equations of infinite order in real domains. Solvability questions of a non-homogeneous convolution equation of a system of non-homogeneous equations are studied. Completely solved is the factorization problem for the convolution operator. Analytic functions of several complex variables are used widely.

For people working in the domain of function theory. Completely accessible for postgraduate students of the mathematical departments of universities.
