Applications of characteristic equation of linear delay difference equations
Hajnalka Péics

Abstract

Linear delay difference equations as well as generalized characteristic equations and their importance at oscillation of all solutions of considered difference equations are studied in this paper. Some results of comparison of solutions of difference equations and inequalities as well as conditions for the existence of positive solutions are presented as the application of the generalized characteristic equation.
