摘要 构造了一个类似于基本解的函数,并且将时间作为检验函数,得出了退化抛物方程的一系列时间衰减估计.此处所有的估计都是建立在初值适当光滑的基础上.从方程的特解可看出,本文得到的时间衰减估计是最优的. We construct a function similar to fundamental solution and use some time test functions to get the time estimates of thedegenerate parabolic equation. In this paper we ask the initial trace to be suitably smooth. Judging from the special solution of the degenerate parabolic equation our estimates are the best.
