Nonsmooth Convex Functionals and Feeble Viscosity Solutions of singular Euler-Lagrange Equations

Nikos Katzourakis

Let F be nonnegative, convex and smooth off a compact set K. We prove that continuous local minimisers of convex functionals are "very weak" viscosity solutions in the sense of Juu…

Nonuniqueness in Vector-Valued Calculus of Variations in $L^{\infty}$ and some Linear Elliptic Systems

Nikos Katzourakis

For a Hamiltonian $H \in C^{2} (R^{N \times n})$ and a map $u : Ω \subseteq R^{n} /! ⟶ R^{N}$ , we consider the supremal functional \[ \label{1} \tag{1…
