摘要

本文研究具有大扩散的抛物型系统的收敛速度问题。我们展示了空间均匀化发生的确切时刻,并通过收敛速率估计了吸引子的连续性。我们给出了一个例子,其中我们的估计是最优的。

Large diffusivity and rate of convergence of attractors in parabolic systems
In this paper, we are concerned with the rate of convergence of parabolic systems with large diffusion. We exhibit the exact moment that spatial homogenization occurs and estimate the continuity of attractors by a rate of convergence. We present an example where our estimate is optimal.
