%X 摘要： 研究了一类二阶非线性差分方程同宿解的存在性。利用临界点理论, 在满足更一般的超线性条件下, 证明了该方程同宿解的多解性。<br>Abstract: We study the existence of homoclinic solutions for a class of second order nonlinear difference equations. Under more general superlinear conditions, we prove the multiplicity results of the equations by using critical point theory
