Partial differential equations (Winter Semester 2004/05)

Lecturer: Professor Guido Schneider
Classes: Lecture (01058), Problem class (01059)
Weekly hours: 4+2
Audience: Mathematicians, physicians, electrical engineering,... (4.-9. semester)

Almost all rules of physics and engineering, many rules in life sciences and economics are formulated as ordinary or partial differential equations. As different as these applications of differential equations are, as different the behavior of their solutions. Therefore, a mathematical theory which wants to cover all differential equations can only cover the absolute basics. Important examples will play the same role as a good mathematical theory for PDEs. We will discuss:

* fundamental examples: Laplace equation, heat equation, first order systems, shocks
* functional analytic tools: Fourier transform, Sobolev spaces, inequalities
* linear and nonlinear PDEs on the real line: transport, diffusion, dispersion, Duhamel's formula, local existence and uniqueness, examples,
* linear and nonlinear PDEs with boundary conditions: periodic, Dirichlet, Neumann, mixed boundary conditions, sectorial operators, spaces of fractional powers, local existence and uniqueness, examples
* the Millenium-problem: The global existence of smooth solutions of the 3D Navier-Stokes problem.
