Partial Differential Equations and Mathematical Physics: The Danish-Swedish by Lars Hörmander and Anders Melin | Mar 28, 1996.

This book is an introduction to partial differential equations (PDEs) and the relevant functional analysis tools which PDEs require. This material is intended for second year graduate students of mathematics and is based on a course taught at Michigan State University for a number of years. • Analysis of Differential Equations can date back as early as the period when Calculus was invented. • 1671: Newton called Fluxional Equations • 1676: Leibniz introduced the term Differential Equations (Aequatio Differentialis, in Latin) • It is fair to say that every subject that uses Calculus involves differential equations.

In this class time is usually at a premium and some of the definitions/concepts require a differential equation and/or its solution so we use the first couple differential equations that we will solve to introduce the definition or concept. Here is a quick list of the topics in this Chapter.
