On the Hessian matrix and Minkowski addition of quasiconvex functions

TL;DR: In this article, the class Q of quasiconvex functions with convex sublevel sets was studied, and the Minkowski addition of these functions was investigated in terms of the support function of the sublevel set.

The Brunn-Minkowski inequality and A Minkowski problem for nonlinear capacity

TL;DR: This article studies two classical potential-theoretic problems in convex geometry and an inequality of Brunn-Minkowski type for a nonlinear capacity in Laplace equation and its solutions in an open set.
Journal ArticleDOI

The p -capacitary Orlicz–Hadamard variational formula and Orlicz–Minkowski problems

TL;DR: In this paper, the p-capacitary Orlicz-Brunn-Minkowski theory was proposed and solved under some mild conditions on the involving functions and measures.
Journal ArticleDOI

On the strict concavity of the harmonic radius in dimension N⩾3

TL;DR: In this paper, a result on the strict concavity of the harmonic radius in open convex domains of R N, for N⩾3, is given, which implies the strict convexity of Robin function and the uniqueness of harmonic center.
Journal ArticleDOI

Smoothness of certain degenerate elliptic equations

John L. Lewis
TL;DR: In this paper, it was shown that if u is nonconstant and real analytic in D, then the gradient of u does not vanish in D. Theorem 1 is false when p = 2.

Multiple integrals in the calculus of variations

TL;DR: In this paper, a variational method in the theory of harmonic integrals has been proposed to solve the -Neumann problem on strongly pseudo-convex manifolds and parametric Integrals two-dimensional problems.
