Symétrie des grandes solutions d'équations elliptiques semi linéaire

Alessio Porretta, Laurent Veron

We prove that, if is a continuous asymptotically convex function, any solution of in a ball B which tends to infinity on is radially symmetric.

Separable p-harmonic functions in a cone and related quasilinear equations on manifolds

Alessio Porretta, Laurent Veron

In considering a class of quasilinear elliptic equations on a Riemannian manifold with nonnegative Ricci curvature, we give a new proof of Tolksdorf's result on the construction of…

Barrier functions for Pucci-Heisenberg operators and applications

Alessandra Cutri, Nicoletta Tchou

The aim of this article is the explicit construction of some barrier functions ("fundamental solutions") for the Pucci-Heisenberg operators. Using these functions we obtain the con…
