Error bounds for asymptotic solutions of second-order linear difference equations. II: The first case.
Existence of multiple positive solutions for discrete problems with -Laplacian via variational methods.
Existence of periodic and almost periodic solutions of abstract retarded functional difference equations in phase spaces.
Existence of positive periodic solutions of higher-order functional difference equations
Based on the fixed-point theorem in a cone and some analysis skill, a new sufficient condition is obtained for the existence of positive periodic solutions for a class of higher-order functional difference equations. An example is used to illustrate the applicability of the main result.
