【摘要】 研究了两种群互惠模型。利用耦合上下解及相应的单调序列方法研究了带Direchlet边界条件互惠模型强耦合问题共存解,结果说明,当交错扩散和种间作用相对弱时,强耦合问题就至少存在一个解。更多还原

【Abstract】 In this paper,the cooperating two—species Lotka—Vorterra model is discussed.The authors study the existence of solutions to a strongly coupled elliptic system with homogeneous of Dirchlet boundary conditions by the method of coupled upper and lower solutions and its as- sociated monotone iterations.Their results shows that this model admits at least one coexis- tence state if cross—diffusions are weak.更多还原
