Research Group for Functional Analysis
The members of our group work in the fields of
Functional analysis, complex analysis, harmonic analysis, operator theory, spectral theory
Our scientific activities focus on
- Spaces with an indefinite metric (Krein- or Pontryagin spaces)
- De Branges' spaces of entire functions
- Operatortheoretic problems of mathematical physics: spectral theory of Schrödinger operators or Hamiltonian systems.
- Interpolationsproblems of classical analysis (positive definite functions, functions with nonnegative real part, etc.), power moment problems
