  • Oscillatory integrals
  • Fourier integral operators and pseudo-differential operators in Euclidean space
  • Pseudo-differential operators on manifolds and their spectral theory, Sobolev spaces
  • Hamilton-Jacobi theory, symplectic geometry, Lagrangian submanifolds
  • Global theory of Fourier integral operators on manifolds

Qualification Goals

The students shall

  • to get to know and use the theory of Fourier integral operators as a central area of analysis and be introduced to questions of current research,
  • Apply knowledge from functional analysis, Fourier and distribution theory to the modern theory of partial differential equations,
  • 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.


None. The competences taught in the following modules are recommended: either Analysis I and Analysis II or Basic Real Analysis, Complex Analysis and Vector Analysis, Functional Analysis, Partial Differential Equations.
