  • 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

Students will

  • Are familiar with the theory of Fourier integral operators as a central area of calculus and can use it,
  • have been introduced to questions of current research,
  • can apply knowledge from functional analysis, Fourier and distribution theory to the modern theory of partial differential equations,
  • 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 Analysis I and Analysis II or Basic Real Analysis, Complex Analysis and Vector Analysis, Functional Analysis, Partial Differential Equations.


The module can be attended at FB12 in study program(s)
