“…for j = 0,1,...,k. Our aim here is to investigate the boundedness character and global attractivity of positive solutions of (1.1), where a j > 0, j = 0,1,...,k, and f j : (0,∞) → (0,∞), j = 0,1,...,k, satisfy conditions (H 1 ) and (H 2 ). Some special cases of (1.1) has been investigated, for example, in [4,5,9,10,12] from which our motivation stems.…”
