Shortly after the completion of this paper, we sadly learned about the passing of Emmanuele DiBenedetto. We wish to humbly dedicate this paper to his memory, with esteem, admiration and gratitude. This is a small token of appreciation for his groundbreaking contributions in the field of Regularity Theory.
We consider a quasilinear degenerate parabolic equation driven by the orthotropic $p-$Laplacian. We prove that local weak solutions are locally Lipschitz continuous in the spatial variable, uniformly in time.
