Regularity for a class of quasilinear degenerate parabolic equations in the Heisenberg group

Luca Capogna, Giovanna Citti, Nicola Garofalo

We extend to the parabolic setting some of the ideas originated with Xiao Zhong's proof in \cite{Zhong} of the Hölder regularity of $p-$harmonic functions in the Heisenberg group $…
