Contents

  • Banach and Hilbert spaces, their dual spaces
  • strong and weak convergence, pre-compactness, convex sets and minimization problems
  • continuous operators, dual operators, operator topologies, Fourier and Laplace transformations
  • Standard theorems of functional analysis
  • Spectrum of bounded operators, Fredholm alternative, Fredholm operators and their index, spectral decomposition of normal operators
  • Unbounded operators: basic questions, differential operators

Qualification Goals

The students shall

  • get to know typical problems of infinite-dimensional theory and their applications,
  • learn on examples like minimization problems how pure and applied mathematics interact,
  • practice mathematical work 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.

Prerequisites

None. The competences taught in the following modules are recommended: either Linear Algebra I and Linear Algebra II or Basic Linear Algebra, either Analysis I and Analysis II or Basic Real Analysis, Measure and Integration Theory.

Please note:

This page describes a module according to the latest valid module guide in Wintersemester 2022/23. Most rules valid for a module are not covered by the examination regulations and can therefore be updated on a semesterly basis. The following versions are available in the online module guide:

The module guide contains all modules, independent of the current event offer. Please compare the current course catalogue in Marvin.
