Partial differential equations (PDEs) arise when the unknown is some function f : Rn!Rm. We are given one or more relationship between the partial derivatives of f, and the goal is to ﬁnd an f that satisﬁes the criteria. PDEs appear in nearly any branch of applied mathematics, and we list just a few below.

That will be done in later sections. The point of this section is only to illustrate how the method works. On interior regularity of the solutions of partial differential equations Substituting into the wave equation, we ﬁnd c2w ˘˘ 2c2w ˘ + c2w = c2 (w ˘˘+ 2w ˘ + w ) 2c2w ˘ = 2c 2w ˘ =)w ˘ = 0 w= f(˘) + g( ) = f(x ct) + g(x+ ct) Another approach: D t= @ @t; D x= @ @x So and the wave equation is (D t+ cD x)(D t D x)u= D2 t c 2D2 t u= u tt c2u xx= 0 Note both (D t D x)u= 0 (D t+ cD x)u= 0 Hörmander, L., Pseudo-differential operators and hypoelliptic equations.

### • 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.
