Abstract
Motivated by some results of L. Berg (2002),
in this paper we find the second member in the asymptotic
development of some of the positive solutions of a class of difference equations
of second and third orders. The main result in this paper partially
solves an open problem by S. Stević (2003), and it is applied to some classes of mathematical biology models,
for example, generalized Beverton-Holt stock recruitment model, flour
beetle population model, mosquito population equations, and discrete delay
logistic difference equation.
