The concentration phenomenon on the high-dimensional sphere and the high-dimensional cube. Approximately Gaussian Marginals and the "thin shell" theorem of Sudakov/Diaconis-Freedman. Log-concavity and Thin Shell estimates, the Prekopa-Leindler inequality, Poincare inequalities through the Bochner technique. The isotropic constant, proof of the Bourgain-Milman inequality.


Real Analysis, Introduction to Hilbert Spaces, Probability (for Mathematicians or for Sciences)

Final grade

The formal assignments are:

  • Solve and submit these exercises. My plan is to add exercises every week or so during the semester.

  • Comments

  • Here is a proof that the level sets of the distance function are null sets (which is not needed for the isoperimetric inequality, but still good to know).
