【摘要】:本文主要討論以下非經(jīng)典擴散方程在非柱形區(qū)域上解的適定性和長時間行為其中Qτ為R4中的非柱型區(qū)域,非線性項f滿足任意次多項式增長條件,外力項g∈Lloc(R; H-1(Ot)).我們首先選擇合適的函數(shù)空間,給出非柱形區(qū)域上方程弱解的定義;然后,我們借助同胚坐標變換建立一系列的先驗估計,從而證明方程在非柱形區(qū)域上弱解的適定性;最后利用壓縮函數(shù)方法給出拉回Dλ1-吸引子的存在性.
[Abstract]:In this paper, we mainly discuss the following nonclassical diffusion equations in the noncylindrical domain, where Q 蟿 is a noncylindrical region in R4, the nonlinear term f satisfies the growth condition of polynomial of any degree, and the external force term g 鈭,
