Abstract
We consider integral functionals in the Heisenberg group, whose convex C 2-integrand has quadratic growth from below, and growth of order q > 2 from above. We prove Hölder regularity for the full gradient of minimizers under the condition that q is less than an explicitly calculated dimension-dependent bound.
