Sneddon’s academic journey took him from the University of Glasgow to the University of Cambridge, and his work was directly informed by real-world problem-solving. During World War II, he served as a Scientific Officer for the Ministry of Supply, where his work focused on the mathematical theory of elasticity in relation to armaments. It is this grounding in practical application that infused his teaching and writing. He later held the prestigious , a position he held from 1956 until his retirement in 1985. His lectures at the university, as well as at the University College of North Staffordshire and to researchers at the English Electric Company, formed the direct foundation for this book.
: Conditions under which a pair of first-order PDEs share a common solution.
Before tackling PDEs directly, this chapter establishes the necessary mathematical groundwork. It begins with the basic geometry of surfaces and curves in three dimensions—concepts that are essential for understanding the geometric interpretation of PDE solutions. The chapter then introduces Pfaffian differential equations and develops the theory of complete, general, and singular integrals. Sneddon places particular emphasis on the properties of ordinary differential equations with more than two variables, noting that parts of this theory play crucial roles in the study of PDEs and must be thoroughly understood before proceeding further.
