  • 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

Students will

  • know typical problems of infinite-dimensional theory and their applications,
  • understand the close interlocking of pure and applied mathematics through examples such as minimization problems,
  • 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.


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.
