Abstract

Introduction Differential and integral forms of isoperimetric inequalities Proof of Theorem 1.1 A relation between the distribution of a function and its derivative A variational problem The discrete version of Theorem 5.1 Proof of propositions 1.3 and 1.5 A special case of Theorem 1.2 The uniform distribution on the sphere Existence of optimal Orlicz spaces Proof of Theorem 1.9 (the case of the sphere) Proof of Theorem 1.9 (the Gaussian case) The isoperimetric problem on the real line Isoperimetry and Sobolev-type inequalities on the real line Extensions of Sobolev-type inequalities to product measures on $\mathbf{R}^{n}$ References.
