Sharp mean Hadamard inequalities and polyconvex integrands that give rise to convex functionals

Analysis of PDEs 2026-04-14 v1

Abstract

We investigate several instances of the Hadamard inequality in the mean in two dimensions. As a consequence, we prove the uniqueness of minimizers of an integral functional with a polyconvex integrand, subject to mixed Dirichlet and Neumann boundary conditions. The theoretical findings are complemented by computational experiments that illustrate the behavior of the minimizers.
