A Special Operational Calculus,As we have already observed, our approach to the study of boundary value problems for partial differential equations by means of reducing them to differential-operator equations is of course also applicable to cases when the operators A.that appear in equation (1), §0, Chapter VI, are neither II- operators nor M-operators.

Function Spaces and Operators Generated by Differentiation,l Euclidean space ℝ". We introduce some essential terminology and specify the nature of the problems that will concern us in what follows. The basic objective of the discussion is, in essence, the methods of associating specific objects of classical analysis with the abstract objects to which Chapter I was devoted.
