We study the oscillatory behavior of the second-order quasi-linear retarded difference equation
under the condition (i.e., the noncanonical form). Unlike most existing results, the oscillatory behavior of this equation is attained by transforming it into an equation in the canonical form. Examples are provided to show the importance of our main results.
Sufficient conditions for the oscillation of some nonlinear difference equations are established.
Some new criteria for the oscillation of third order nonlinear neutral difference equations of the form
and
are established. Some examples are presented to illustrate the main results.
We obtain some new sufficient conditions for the oscillation of the solutions of the second-order quasilinear difference equations with delay and advanced neutral terms. The results established in this paper are applicable to equations whose neutral coefficients are unbounded. Thus, the results obtained here are new and complement some known results reported in the literature. Examples are also given to illustrate the applicability and strength of the obtained conditions over the known ones.
Sufficient conditions are obtained for the third order nonlinear delay difference equation of the form
to have property or to be oscillatory. These conditions improve and complement many known results reported in the literature. Examples are provided to illustrate the importance of the main results.
This paper is concerned with the oscillatory behavior of first-order nonlinear difference equations with variable deviating arguments. The corresponding difference equations of both retarded and advanced type are studied. Examples illustrating the results are also given.
In this paper, sufficient conditions are obtained for oscillation of all solutions of third order difference equations of the form
These results are generalization of the results concerning difference equations with constant coefficients
Oscillation, nonoscillation and disconjugacy of a certain class of linear third order difference equations are discussed with help of a class of linear second order difference equations.
