2015 Advances in Difference Equations  
Sufficient conditions which guarantee the oscillation of all solutions of difference equations with oscillating coefficients and several deviating arguments are presented. The corresponding difference equations of both retarded and advanced type are studied. Examples illustrating the results are also given. w = -min n≥ τ i (n) :  ≤ i ≤ m .
