Periodic Solutions for a Class of Second-Order Difference Systems with Variable Exponent
【摘要】 探究了离散p(k)-Laplace系统周期边值问题解的存在性.在一类广义次二次条件下,利用鞍点定理获得了周期解的存在性结果,并举例说明了可解性条件的有效性.
【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 periodic solutions are obtained by using the saddle point theorem, and the validity of the solvability conditions is proved.
