A singular minimizer of a smooth strongly polyconvex functional in two dimensions

André Guerra, Riccardo Tione

We construct a Lipschitz, non- $C^{1}$ map $u : R^{2} \to R^{6}$ which is the unique global minimizer of a smooth, strongly polyconvex functional. Such an example is…

Hyperbolic regularization effects for degenerate elliptic equations

Xavier Lamy, Riccardo Tione

This paper investigates the regularity of Lipschitz solutions $u$ to the general two-dimensional equation $div (G (D u)) = 0$ with highly degenerate ellipticity. Just assuming st…
