• Operator semigroups
• Intrinsic ultracontractivity of Schrödinger semigroups

Further foci of my education:

• Spectral theory
• Funktional analysis
• Complex analysis
• Fourier analysis

• 26. ISEM "Graphs and Discrete Dirichlet Spaces"
• 25. ISEM "Spectral Theory for Operators and Semigroups" (talk: "SPECTRA OF SELF-ADJOINT OPERATORS GENERATING SEMIGROUPS THAT
  SATISFY GAUSSIAN ESTIMATES")

Interested students are welcome to contact me for an application of the next ISEM.
