一类一阶离散周期边值问题的多解性
Multiplicity of positive solutions in a class of first-order discrete periodic boundary-value problems
【摘要】 利用锥上的不动点指标理论对一类一阶离散周期边值问题的正解的存在性进行讨论,得到该问题存在两个正解的充分条件.
【Abstract】 The existence of multiple positive solutions to a class of first-order discrete periodic boundary-value problems was discussed by using the index theory of fixed-point on cone,and the sufficient condition of existence of two positive solutions of this problem was obtained.
