This course gives an introduction to Fourier analysis and real harmonic analysis. Harmonic analysis has its origin in Fourier's work, which provides explicit solutions for e.g. heat and wave equations. Nowadays, it provides important tools in tackling a large variety of problems coming from partial differential equation, in particular for boundary value problems on spaces. Topics of the course include summability of Fourier series, the Fourier transform on , interpolation methods, singular integral operators, and Fourier multipliers.
- Fourier series
- Fourier transform on and
- Tempered distributions and Fourier transforms
- Explicit solutions of heat equation, wave equation and Schrödinger equation on
- Hilbert transform
- Interpolation theorem of Marcinkiewicz
- Singular integral operators
- Mihlin multiplier theorem
Basic knowledge in Functional Analysis is recommended.
Oral exam of approx. 30 minutes.
