Hörmander took a one-year break for military service from 1953 to 1954, but due to his position in defense research was able to proceed with his studies even during that time. In mathematics, Hörmander's condition is a property of vector fields that, if satisfied, has many useful consequences in the theory of partial and stochastic differential equations. The condition is named after the Swedish mathematician Lars Hörmander For partial di erential equations the corresponding representation is u(x) = Z P(˘)=0 ei(x;˘) (d˘); (2) where is an arbitrary distribution from a certain class.

• 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. HÃ¶rmanderÂ¿s lifetime work has been devoted to the study of partial differential equations and its applications in complex analysis. In 1962 he was awarded the Fields Medal for his contributions to the general theory of linear partial differential operators.

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.

PARTIAL DIFFERENTIAL EQUATIONS 3 For example, if we assume the distribution is steady-state, i.e., not changing with time, then ∂w = 0 (steady-state condition) ∂t and the two-dimensional heat equation would turn into the two-dimensional Laplace equa tion (1).

This chapter focuses on partial differential equations that model localized patterns and structures appearing on interfaces between complex flows. They occur in quasi-planar flame fronts, thin viscous fluid films flowing over inclined planes, and the dendritic phase change fronts in binary alloy mixtures.

The aim of this book is to give a systematic study of questions con cerning existence, uniqueness and regularity of solutions of linear partial differential equations and boundary problems. Let us note explicitly that this program does not contain such topics as eigenfunction expan sions, although we do give the main facts concerning differential operators which are required for their study.
