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.

The formal assignments are: 

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

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).
