This monograph provides the theoretical foundations needed for the construction of fundamental solutions and fundamental matrices of (systems of) linear partial

A self-contained and systematic development of an aspect of analysis which deals with the theory of fundamental solutions for differential operators, and their

Our understanding of the fundamental processes of the natural world is based to a large extent on partial differential equations (PDEs). The second edition of P

Originally published in 1961, this Classics edition continues to be appealing because it describes a large number of techniques still useful today. Although the

Two general questions regarding partial differential equations are explored in detail in this volume of the Encyclopaedia. The first is the Cauchy problem, and
