Partial Differential Equations 2

Summer Term 2019

Relevance: The course is eligible as a part of the master in Mathematics, Mathematical Physics, Industrial Mathematics, or Economathematics and is recommended to everyone with interests in analysis. Clearly, other interested participants are also very welcome.

ECTS points: The module (consisting of the lecture and the exercise class) has a worth of 12 ECTS points.

Prerequisites: The lecture builds on basic knowledge in analysis (including the theory of Lebesgue integration) and linear algebra. Some experience with either PDEs or analysis is general is recommended. It is not absolutely necessary, however, to have attended the preceding PDE lecture.

Contents

It is planned to cover the following topics:

  • maximum principles for linear differential operators
    • maximum principles and estimates
    • Hopf boundary point lemma
    • variants for non-linear equations
  • weak differentiability
    • definition and characterization of weak derivatives
    • examples
    • calculus rules
  • Sobolev spaces
    • definition
    • functional-analysis properties
    • Meyers-Serrin theorem
    • Sobolev embeddings
    • Poincaré inequalities
    • Rellich theorem
  • L2-theory for linear elliptic PDE systems
    • abstract description of boundary values problems
    • coercivity
    • Lax-Milgram lemma
    • L2 existence theory
  • regularity theory for linear elliptic PDEs and PDE systsms (selected topics, as time permits).
