Periodic solutions for a class of higher-order difference equations Huantao Zhu1 and Weibing Wang 2 1 Hunan College of Information Changsha Hunan 410200 . China 2Department of Mathematics Hunan University of Science and Technology Xiangtan Hunan 411201 . China Corresponding author gfwwbing@ Email address HZ zhu-huan-tao@ Abstract In this article we discuss the existence of periodic solutions for the higher-order di erence equation x n k g x n f n x n T n . We show the existence of periodic solutions by using Schauder s fixed point theorem and illustrate three examples. MSC 2010 39A10 39A12. Keywords functional difference equation
