一类四阶差分方程边值问题的多解性
Existence of Multiple Positive Solutions of Boundary Value Problem for a Fourth-order Difference Equation
【摘要】 利用锥上的不动点定理,讨论一类四阶差分方程边值问题的多解性.建立了该问题存在2个正解的充分条件.
【Abstract】 By using the fixed point theorem on the cone,we consider the multiplicity of positive solutions for a class of boundary value problem of fourth-order difference equations.Sufficient conditions are established so that there exist two positive solutions.
