Subject of this lecture are the spectral theory of bounded and unbounded operators on Hilbert spaces, as well as elements of scattering theory. Specifically, the following contents will be discussed:

  • The functional calculus for bounded and unbounded operators (elementary theory of C^* algebras, Gelfand-Naimark duality)
  • The Spectral Theorem for bounded and unbounded Operators
  • Existence and completeness of wave operators for trace class perturbations and the invariance principle (theorem of Kato-Rosenblum)

Qualification Goals

Students will

  • learn to recognize and appreciate the relevance of spectral analytical methods to concrete problems, such as those from the theory of partial differential equations, and acquire the appropriate tools for solving these problems,
  • learn how methods of algebra, analysis, geometry, and topology interact,
  • re-evaluate knowledge gained in the basic modules and some advanced modules (e.g., Theory of Functions, Analysis III, and Functional Analysis),
  • recognize the relationships of spectral theory to other areas of mathematics and to other sciences.
  • practice mathematical ways of working (developing mathematical intuition and its formal justification, training the ability to abstract, reasoning)
  • improve their oral communication skills in exercises by practicing free speech in front of an audience and in discussion.


Translation is missing. Here is the German original:

Keine. Empfohlen werden die Kompetenzen, die in den Grundmodulen vermittelt werden. Kenntnisse aus der allgemeinen Maß- und Integrationstheorie sowie der Funktionentheorie und Funktionalanalysis sind hilfreich.


The module can be attended at FB12 in study program(s)

  • B.Sc. Mathematics
  • M.Sc. Mathematics
  • LAaG Mathematics

When studying M.Sc. Mathematics, this module can be attended in the study area Specialization Modules in Mathematics.

The module can also be used in other study programs (export module).

Die Wahlmöglichkeit des Moduls ist dadurch beschränkt, dass es der Reinen Mathematics zugeordnet ist.
