MATE 6677   Partial Differential Equations


Time and place
MJ 9:00--10:15, in M-118. On Friday Dec 17, we meet in M-118 at 7:30pm. The final exam is on Jan 15 at 11:00; the second exam is ready for you to collect.
Prerequisites
According to university policy, officially, none. In effect, the student is expected to have a good background in Advanced calculus and basic topology, an introductory course in Ordinary differential equations, and having taken, or taking concurrently, a course in Real analysis. For an introductory course emphasizing solution methods in a classical setting, the student is encouraged to take or audit MATE 6675.
Topics
We will mainly follow the plan of Folland:
Preliminaries: notation and definitions, some function spaces, convolution, Fourier transform, distributions.
Local existence theory: basic concepts, real first-order equations, the general Cauchy problem, Cauchy-Kovaleskaya theorem.
The Laplace operator: basic properties of harmonic functions, fundamental solution, Dirichlet and Neumann problems, Green's function, Dirichlet problem in a ball and half-space.
The heat operator: heat kernel, heat equation in bounded domains.
The wave operator: Cauchy problem, solutions in a half-space, inhomogeneous equation, the wave equation in bounded domains, Radon transform.
The L^2 theory of derivatives: Sobolev spaces on R^n, local regularity of elliptic operators, Sobolev spaces on bounded domains.
Some topics from integral equations or L^2 methods for elliptic boundary-value problems.
