Wt. Li et al., Existence and asymptotic behavior of positive solutions of higher-order nonlinear difference equations with delay, MATH COMP M, 29(9), 1999, pp. 39-47
Classification schemes for positive solutions of a class of higher-order no
nlinear difference equations with delay are given in terms of their asympto
tic behavior, and necessary as well as sufficient conditions for the existe
nce of these solutions are also provided. (C) 1999 Elsevier Science Ltd. Al
