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.

采用上下解及相應(yīng)的單調(diào)迭代序列的方法，結(jié)合Schauder不動點定理，研究帶Dirichlet邊界條件的兩種群的互惠模型強耦合問題共存解www.插逼com。

In chapter 4, we first discussed the existence of multiple positive solutions of the second order nonsingular Dirichlet boundary value problem for impulsive differential equations by using the fixed point index theorem in cones . Next, we presented some new existence results for singular boundary value problems for second order impulsive differential equations by using fixed point theorem in cones and Leray-Schauder nonlinear alternative theorem.

第四章我們首先利用錐不動點定理討論了非奇異二階脈沖微分方程狄利克萊邊值問題多個正解的存在性；其次我們用錐不動點定理和Leray-Schauder型非線性抉擇定理永久网站操，討論了奇異二階脈沖微分方程狄利克萊邊值問題一個及多個正解的存在性午夜三级永久久久。

We use the idea of isothermal parameter representation to prove a convergence theorem, which serves as an important theoretical base of studying the problem of rational Bézier surface.

運用等溫參數(shù)化思想證明了一個收斂定理，作為用Dirichlet能量函數(shù)方法研究有理Bézier極小曲面問題的重要理論基礎(chǔ)欧美性爱黄页。

This paper was concerned with the Dirichlet-Neumann mixed boundary value problem of bipolar quantum hydrodynamic model in thermal equilibrium. By truncation method and Leray-Schauder fixed point theorem, the existence of solution to the problem is proved. In addition, the uniqueness of the solution was proved as the Plank constant was large enough.
