Gaussian Isoperimetry and Related Topics I

Explore the fundamental concepts of Gaussian isoperimetry and its wide-ranging applications in this 50-minute lecture by Joe Neeman at the Hausdorff Center for Mathematics. Delve into the Gaussian isoperimetric inequality, which provides a sharp lower bound on the Gaussian surface area of any set in relation to its Gaussian measure. Understand how its dimension-independent nature makes it a powerful tool for proving concentration inequalities in high dimensions. Discover the various consequences of Gaussian isoperimetry and its connections to other areas of mathematics. Examine applications in probability, including concentration and Gaussian noise stability. In the realm of analysis, learn how the Gaussian isoperimetric inequality is equivalent to a specific Sobolev-type inequality. Finally, witness the proof of the Gaussian isoperimetric inequality and some of its stronger versions using methods from geometric measure theory.
