摘要 应用能量估计方法和Gagliardo-Nirenberg型不等式证明一类具有性别结构的交错扩散捕食者-食饵模型的整体解的存在性和一致有界性,并通过构造Lyapunov函数给出该模型正平衡点全局渐近稳定的充分条件. Using the energy estimate and Gagliardo-Nirenberg-type inequalities,the existence and uniform boundedness of global solutions for a cross-diffusion predator-prey system with sex-structure are proved.A sufficient condition of global asymptotic stability of the positive equilibrium point for the model is given by constructing Lyapunov function.
