一类变指数二阶差分系统的周期解
Periodic Solutions for a Class of Second-Order Difference Systems with Variable Exponent
摘要
Abstract
This paper investigates the existence of solutions for periodic boundary value of discrete p(k)-Laplacian systems.Under the generalized subquadratic conditions,some results for the existence of peri-odic solutions are obtained by using the saddle point theorem,and the validity of the solvability condi-tions is proved.关键词
