摘要
对于经典的零通量趋化-消耗模型 \begin{equation*} u_t= \Delta u - \chi \nabla \cdot (u \nabla v) \quad \textrm{and}\quad v_t=\Delta v- uv, \quad \text{ with } (x,t)\in \Omega \times (0,T_{max}), \end{equation*} 其中 是 中有界光滑区域,, 为某正数且 ,Tao在一篇论文中建立了如下结论:对每一组充分正则的初始数据 和 ,存在 使得对所有 ,该初边值问题在 中有唯一有界经典解。本文在 时,对更大的常数 取值也得到了相同结论。
