Abstract

We give a proof of H ̈older continuity for bounded local weak solutions to the equation

ut =\sum_{i=1}^N (|u_{x_i}|^{p_i−2} u_{x_i} )_{x_i} , in Ω × [0, T], with Ω ⊂⊂ R^N

under the condition 2 < pi < p(1 + 2/N) for each i = 1, .., N, being p the harmonic mean of the pi's, via
recently discovered intrinsic Harnack estimates. Moreover we establish equivalent forms of these Harnack
estimates within the proper intrinsic geometry.
