Analysis of Functions (Part II D-course)

The analysis of functions has its roots in the rigorous study of the equations of mathematical physics, and is now a key part of modern mathematics. This course builds on the Part II courses Linear Analysis and Probability & Measure, applying the theory of integration and the tools of functional analysis to explore such topics as Lebesgue and Sobolev spaces, the Fourier transform and the generalised derivative. These topics are important and interesting in themselves, but the emphasis is on their use in other areas of mathematics (for instance in the representation of functions and in partial differential equations), rather than their maximal generalisation. You can get an idea of the flavour of the course by browsing the Analysis by Lieb & Loss (Springer).

Prerequisites: A good understanding of the methods and results in the IB courses Linear Algebra, Analysis II and Metric and Topological Spaces is essential. Part II Linear Analysis and integration theory from Part II Probability and Measure are essential.

Attack of the Boltzmann Brains (Jim Kakalios)

Sources: Some parts of these lecture notes owe a lot to two sets of hand-written lecture notes on kinetic equations written by Laure Saint-Raymond and Laurent Desvillettes, as well as to the lecture notes available online of G. Allaire and F. Golse on transport and diffusion processes. They also inspire from the classical books of R. Glassey, of C. Cercignani, and of C. Cercignani – R. Illner – M. Pulvirenti, as well as from various recent research papers. Many thanks to Otis Chodosh, who typewrote a first latex version of these notes.

Some significant parts of these lecture notes are borrowed from some lecture notes previously written by Mihalis Dafermos for this CCA course, and from some lecture notes I wrote for a similar course I gave in Paris-Dauphine 2006-2009. The lecture notes are also strongly inspired by the books of C. Evans, E. Lieb & M. Loss, W. Strauss, F. John, by the review paper Partial differential equations of S. Klainerman, and by various lecture notes available online by L. Boutet de Monvel, B. Driver, B. Helffer, G. Tsogtgerel and C. Villani.
