摘要
用一类锥不动点定理首先给出一阶差分周期边值问题的存在性原则,并应用此原则论证了该问题一个或多个正解的存在性,最后通过例证对该问题加以说明。
The existence principle of single and multiple positive solutions for the first order discrete periodic boundary value problems was studied by employing a fixed point theorem in cones.Based on this principle,the existence of single and multiple positive solutions for the problems was given.Some new results about nonlinear difference equations on a finite discrete segment with periodic boundary conditions were demonstrated.
