Differential Equations II A

Homepage of the lecture
ISIS webpage of the lecture

This lecture provides an introduction to boundary value problems for linear and nonlinear elliptic differential equations of second order. We will discuss Sobolev spaces, which rely on a generalized notion of differentiability, variational problems and the associated operator equations, monotone operators, Galerkin methods and linear finite elements as well as the Lax-Milgram lemma and the theorem of Zarantonello.

This 2-hour lecture will be held weekly and is worth 5 ECTS.

Differential Equations III

Homepage of the lecture
ISIS-webpage of the lecture

The subject of the lecture are initial boundary value problems for partial differential equations describing instationary processes. Using the variational approach and the theory of monotone operators, linear and nonlinear evolution equations of first and second order are studied.In addition to statements on the existence, uniqueness and stability of solutions, aspects of the approximate solution are also considered. Equations of fluid mechanics (Navier-Stokes equations, generalized Newtonian fluids) and elasticity theory and mechanics (vibrating membrane with damping) are considered as applications.

Bochner integral and Bochner-Lebesgue spaces, Gelfand triplets, Sobolev spaces for abstract functions, and compactness arguments for families of abstract functions (Lions-Aubin theorem and generalizations), among others, are provided as functional analytical foundations.
