A Survey on the Oscillation of Difference Equations with Constant Delays

In this survey, necessary and sufficient conditions for the oscillation of all solutions of delay difference equations with one or several constant arguments, in terms of the characteristic equation, are presented. Explicit necessary and sufficient conditions (in terms of the constant coefficient...

Description
Summary:In this survey, necessary and sufficient conditions for the oscillation of all solutions of delay difference equations with one or several constant arguments, in terms of the characteristic equation, are presented. Explicit necessary and sufficient conditions (in terms of the constant coefficient and constant argument only) are also presented in the case of one constant argument. In the case of several arguments explicit but sufficient conditions only are given. In this case the results are also extended to equations with variable coefficients.
