| Summary | This course is an introduction to analytical treatment of dispersive partial differential equations. In particular, the course focuses on the theoretical study of the nonlinear Schrödinger equations (NLS). The students will first learn Fourier transform, relevant function spaces and useful inequalities, and then use them to prove existence of unique solutions to NLS and further study their long time behaviour. The course aims to provide a glimpse of analysis in the theory of PDEs. |
| Course description |
- Review of the following topics: Lebesgue spaces, Hölder, Minkowski (integral) and interpolation inequalities. Fourier transform: Plancherel identity, Hausdorff-Young's inequality. Convolution: Young's inequality, duality of products and convolutions under Fourier transform
- (fractional) Sobolev spaces: Sobolev embedding theorem via Fourier transform, algebra property of Sobolev spaces
- space-time function spaces
- local well-posedness (I): via Sobolev embedding and Banach fixed point theorem
- virial identity, finite-time blowup solutions
- linear solutions: dispersive estimate, Strichartz estimate
- local well-posedness (II): via Strichartz estimate
- conservation laws, global existence
- a glimpse of scattering theory
The main focus is on how to use inequalities and establish estimates. Hence, some inequalities will be given without proofs and some operations such as switching limits and integrals will be performed without rigorous justifications.
