Positive Solutions of a Neutral Difference Equation with Positive and Negative Coefficients

Abstract:
A neutral difference equation with positive and negative coefficients is a natural model for a population with depletion of the aged. In this paper, we obtain conditions which are sufficient for one such equation to support an eventually positive population.

Keywords:
Neutral difference equation, positive solution.
