Existence of Multiple Monotone Positive Solutions for Higher order Boundary Value Problems That Contain All Order Derivatives
【摘要】 利用五个泛函的不动点定理,研究一类含有各阶导数的2m阶微分方程边值问题的三个单调正解的存在性.
【Abstract】 By using the five functions fixed point theorem,we establish the existence of three monotone positive solutions for a class of 2mth order boundary value problems that contain all order derivatives.
