本文考虑一致抛物方程和Hamilton-Jacobi方程的柯西问题。我们的目的是证明每个Cauchy问题解的梯度的L∞-范数的上估计的最优性。为了达到这个目的,我们研究了这个L∞-范数的一个较低的估计.
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.
