This paper presents a new sufficient condition for the oscillation of all solutions of difference equations with several deviating arguments and oscillating coefficients. Corresponding difference equations of both retarded and advanced type are studied. Examples illustrating the results are also given.
Keywords: difference equations, retarded argument, advanced argument, oscillatory solutions, nonoscillatory solutions, oscillating coefficients
