Sobolev Inequalities: Symmetrization and Self Improvement via Truncation

We develop a new method to obtain symmetrization inequalities of Sobolev type. Our approach leads to new inequalities and considerable simplification in the theory of embeddings of Sobolev spaces based on rearrangement invariant spaces.

Isoperimetry and Symmetrization for Sobolev Spaces on Metric Spaces

This is a follow up to our recent work [10], where we obtained new symmetrization inequalities for Sobolev functions that compare the rearrangement of a function with the rearrangement of its gradient, and incorporate in their formulation the isoperimetric profile (cf. (2.1) below). These inequalities imply in a straightforward fashion functional inequalities for very general rearrangement inva...

In our recent paper [12] we developed a new principle of “symmetrization by truncation” to obtain symmetrization inequalities of Sobolev type via truncation. In this note we consider the corresponding results for Sobolev spaces on domains, without assuming that the Sobolev functions vanish at the boundary. The explicit connection between Sobolev-Poincaré inequalities and isoperimetric inequalit...

Sharp Geometric and Functional Inequalities in Metric Measure Spaces with Lower Ricci Curvature Bounds

Abstract. For metric measure spaces verifying the reduced curvature-dimension condition CD∗(K,N) we prove a series of sharp functional inequalities under the additional assumption of essentially nonbranching. Examples of spaces entering this framework are (weighted) Riemannian manifolds satisfying lower Ricci curvature bounds and their measured Gromov Hausdorff limits, Alexandrov spaces satisfy...
