Abstract

In this paper we establish the existence of Lipschitz-continuous solutions to the Cauchy Dirichlet problem of evolutionary partial differential equations ∂tu − div Df (Du) = 0 in T, u = uo on ∂PT. The only assumptions needed are the convexity of the generating function f : Rn → R, and the classical bounded slope condition on the initial and the lateral boundary datum uo ∈ W1,∞(). We emphasize that no growth conditions are assumed on f and that – an example which does not enter in the elliptic case – uo could be any Lipschitz initial and boundary datum, vanishing at the boundary ∂, and the boundary may contain flat parts, for instance could be a rectangle in Rn.
