摘要
本文讨论了具有弱奇异灵敏性和Logistic来源的抛物-椭圆型化学趋化竞争系统的正解的长期行为:\n\n\begin{equation} \label{abstract-eq} \begin{cases} u_t=\Delta u-\chi \nabla\cdot (\frac{u}{v^{\lambda}} \nabla v) +ru- \mu u^2, \quad &x\in \Omega,\cr 0=\Delta v- \alpha v +\beta u,\quad &x\in \Omega, \cr \frac{\partial u}{\partial \nu}=\frac{\partial v}{\partial \nu}=0,\quad &x\in\partial\Omega, \end{cases}\, \end{cases}\n\n其中, 为光滑有界域,参数 为正常数, 在本文中,对于所有足够光滑的初始数据 且 已证明:首先,在 时,任何全局定义的正解在 中有界,其中 接着,在 时,任何全局定义的经典解全局有界。第三,在 时,任何全局定义的正解最终在由与初始函数 无关的正数常数上均有界。最后,在 时,任何全局有界的经典解对系统 (0.1) 指数收敛于常数稳态

备注
There are significant errors in the proof of Theorem 1.1, which affect all the subsequent results. Unfortunately, these errors cannot be corrected. Therefore, it should be withdrawn from the system
