考虑反应扩散方程:ut − h2 Δu + Φ(u)= 0,其中Φ是一个偶数势的导数,h是一个小参数。如果初始数据有一个光滑的非临界零点集,我们证明了一个界面在时间O(log(h−1))出现,并且解至少在时间O(1/log h)内保持接近它。
Consider the reaction-diffusion equation in ℝN × ℝ+: ut − h2 Δu + Φ(u) = 0, where Φ 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/√h).
