【摘要】 采用上下解及相应的单调迭代序列的方法,结合Schauder不动点定理,研究带Dirichlet边界条件的两种群的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】 This paper deals with a two-species mutualistic model.With the method of upper and lower solutions,its associated monotone iterations and the fixed point theorem,the coexistence solutions to a strongly coupled elliptic system are studied.Our results show that this model possesses at least one coexistence state if cross-diffusions and cross-reactions are weak.更多还原
