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

The students shall

  • learn to recognize and assess the relevance of spectral analytical methods for concrete problems, e.g. from the theory of partial differential equations, and to acquire the appropriate instruments for solving these problems,
  • learn how methods of algebra, analysis, geometry and topology interact,
  • Re-evaluate contents from the basic modules and some advanced modules (e.g. function theory, Analysis III and functional analysis),
  • to understand the relations of spectral theory to other fields of mathematics and other sciences,
  • practice mathematical working methods (development of mathematical intuition and its formal justification, training of the ability to abstract, proof techniques),
  • improve their oral communication skills in the exercises by practicing free speech in front of an audience and during discussion.
