Contents
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
- correctly recognize and appreciate the relevance of spectral analytical methods to concrete problems, such as those from the theory of partial differential equations, and possess the appropriate tools for solving these problems,
- understand how methods of algebra, analysis, geometry and topology interact,
- re-evaluate their knowledge from the basic modules and some advanced modules (e.g., function theory and vector analysis and functional analysis),
- recognize the relationships of spectral theory to other areas of mathematics and to other sciences,
- have deepened mathematical working methods (developing mathematical intuition and its formal justification, abstraction, proof),
- have improved their oral communication skills in exercises by practicing free speech in front of an audience and in discussion.
