摘要：

Consider the reaction-diffusion equation in R(n) x R+:u(t)-h2-DELTA-u + phi(u) = 0, where phi is the derivative of a bistable even potential, and h is a small parameter. If the initial data have a smooth noncritical zero set, we prove that an interface appears in time O(log(h-1)), and that the solution stays close to it for at least time O(1/square-root-h).
