Existence of Periodic Solutions for A 2n Th-ordern Oolinear Difference Equation
Abstract：In this paper, the existence and multiplicity of solutions for a difference equation of the form △^n（rt-n△^n xt-n）＋f（t,xi）=0（1,1） is discussed by means of variational method, the critical point theory, especially critical group and the Morse theory of nonlinear functional analysis.
