The Cauchy problem for the parabolic \(p\)-Laplacian equation is considered. The authors prove a nonlinear concavity estimate for the pressure away from the maximum point provided the initial data are nonnegative, continuous and compactly supported. This estimate implies (among other things) the convexity of the support for large time.
