Goal of the stay

The goal of the secondment has been to study a suitable regularity theory for subelliptic p-Laplacian operators. In particular, we prove Holder regularity of the gradient for solution of a degenerate p-laplacian equation in contact manifolds, expressed as p-laplacian like operator, with variable coefficients in the Heisenberg group.
