Abstract: This paper considers the existence and multiplicity of positive periodic solutions for a class of nonlinear third-order difference equationΔ3u(t-3)+αΔ2u(t-2)+βΔu(t-1)=f(t,u(t)), t∈[3,T]Z,where T>4, α>0, -1<β<0, f:[3,T]Z×[0,∞)→R is continuous with respect to u∈[0,∞), f(t+ω,u)=f(t,u), ω∈Z+. The proof of the main results is based on Guo-Krasnoselskii fixed point theorem.
