In this paper, we consider the Cauchy problems for a uniformly parabolic equation and a Hamilton–Jacobi equation. Our aim is to show the optimality of an upper estimate of the L∞-norm of the gradient of solution to each Cauchy problem. In order to achieve this aim, we investigate a lower estimate of this L∞-norm.
