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

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 Juutinen-Lindqvist of the highly singular Euler-Lagrange PDE expanded. The hypotheses on F do not guarrantee existence of minimising weak solutions and include the singular p-Laplacian for 1
