Distribution and interpolation spaces

MATH-502 / 5 credits

Teacher: Michelat Alexis Paul Benjamin

Language: English

Remark: Cours donné en alternance tous les deux ans

Summary

The goal of this course is to give an introduction to the theory of distributions and cover the fundamental results of Sobolev spaces including fractional spaces that appear in the interpolation theory. Those notions are central to the study of partial differential equations (PDE).

Content

Part 1: Toplogy and functional spaces. Fundamental theorems on Banach spaces, weak topology, weak * topology, reflexive spaces, separable spaces.

Part 2: Distributions. Topological vector spaces, distributions: differentiation, restriction, localisation, convolution, tempered distributions and Fourier transform.

Part 3: Sobolev spaces. Extension operators, Sobolev embedding theorem, Sobolev inequality, Poincaré inequality, dual Sobolev space, Hilbert-Sobolev spaces, fractional derivatives, fractional Sobolev spaces.

Keywords

Distributions, Sobolev Spaces, Interpolation Spaces
