二阶两点微分方程系统多个正解的存在性
Existence of Multiple Positive Solutions for Systems of Second-order Two-point ODE
【摘要】 利用一个改进的L eggett-W illiam s不动点定理,在f,g满足一定增长条件的前提下,证明了一类二阶两点微分方程系统边值问题:三个正解的存在性.其中:f,g:[0,1]×[0,∞)×R→[0,∞)连续.
【Abstract】 By the uses of an improved Leggett-Williams fixed-point theorem,and imposes some growth conditions on f,g.The existence of three positive solutions of the BVP for systems of second-oder two-point ODE with the form is continuous.
