Abstract

Here we generalize quasilinear parabolic pp-Laplacian type equations to obtain the prototype equation as utdiv(g(Du)/DuDu)=0, u_t - \text{div} (g(|Du|)/ |Du| \cdot Du) = 0, where a nonnegative, increasing, and continuous function gg trapped in between two power functions Dug01|Du|^{g_0 -1} and Dug11|Du|^{g_1 -1} with 1<g0g1<1<g_0 \leq g_1 < \infty. Through this generalization in the setting from Orlicz spaces, we provide a uniform proof with a single geometric setting that a bounded weak solution is locally H\"{o}lder continuous considering 1<g0g121 < g_0 \leq g_1 \leq 2 and 2g0g1<2 \leq g_0 \leq g_1 < \infty separately. By using geometric characters, our proof does not rely on any of alternatives which is based on the size of solutions.
