Lipschitz regularity for solutions of the parabolic -Laplacian in the Heisenberg group
arXiv:2106.05998
Abstract
We prove local Lipschitz regularity for weak solutions to a class of degenerate parabolic PDEs modeled on the parabolic -Laplacian $$\p_t u= \sum_{i=1}^{2n} X_i (|\nabla_0 u|^{p-2} X_i u),$$ in a cylinder , where is domain in the Heisenberg group $\Hn$, and . The result continues to hold in the more general setting of contact sub-Riemannian manifolds.
