Abstract

New sharp Lorentz–Sobolev inequalities are obtained by convexifying level sets in Lorentz integrals via the L p Minkowski problem. New L p isocapacitary and isoperimetric inequalities are proved for Lipschitz star bodies. It is shown that the sharp convex Lorentz–Sobolev inequalities are analytic analogues of isocapacitary and isoperimetric inequalities.
