S. H. Saker, A. M. El-Shenhab: Oscillation criteria for first order delay dynamic equations, 475-489

Abstract:

In this paper, we establish some new sufficient conditions for oscillation of solutions of first order delay dynamic equations on time scales. The results not only contains some well-known criteria for delay differential equations and delay difference equations as special cases but also improve some results obtained on time scales. The main results are obtained by making use of a new algebraic inequality and the analysis of the characteristic inequality.

Key Words: oscillation, first order delay dynamic equations, time scales.
