We analyze some configurations of the general chemotaxis predator–prey model with pursuit-evasion dynamics in with Neumann boundary condition and non-negative initial data, where and are the predator’s and the prey’s pheromone, respectively, modeled by parabolic or elliptic equations, and , with , is a smooth bounded domain. We assume and to be smooth positive functions satisfying and when , smooth non-negative functions such that when and for all , with or . We also assume and to be smooth with , , , , , , for , , , . We prove that for and satisfying some relation there exists a unique classical solution to the system which is global in time and bounded. The result in independent on .

我们利用逃避动力学分析了一般趋化性捕食-被捕食模型的一些结构 在 带有Neumann边界条件和非负初始数据,其中 和 是分别由抛物线或椭圆方程建模的掠食者和猎物的信息素,以及 ,带有 是平滑的有界域。我们猜测 和 使人满意的积极作用 和 什么时候 , 使非负函数平滑,从而 什么时候 和 对所有人 ,带有 要么 。我们还假设 和 与 , , , , , ,对于 , , , 。我们证明 和 满足某种关系,该系统存在一个独特的经典解决方案,该解决方案在时间上是全局的并且是有界的。结果独立。
