MA8106 Harmonic Analysis Spring Semester 2016
There will be a first meeting in room 922 in SB2 on January 5 at 10:15 a.m. A main purpose of this meeting will be to fix 4 weekly hours for lectures and exercises.
Book: Camil Muscalu and Wilhelm Schlag, “Classical and Multilinear Harmonic Analysis", Cambridge Studies in Advanced Mathematics Vol. 137, Cambridge University Press, Cambridge, 2013
We might consider topics from Volume 2 as well, but this will be decided later. The first volume starts with classical one-dimensional topics such as Fourier series, harmonic functions, and the Hilbert transform. Then the higher-dimensional Calderón–Zygmund and Littlewood–Paley theories are developed. Probabilistic methods and their applications are discussed, as well as applications of harmonic analysis to partial differential equations. The volume concludes with an introduction to Weyl calculus.
