摘要:
In this paper, the qualitative behavior of solutions of the bobwhite quail population model x(n+1) = ax(n) + bx(n)/(1 x(n-k)(p))(c), n = 0, 1, ..., where 0 < a < 1 < a + b, p, c is an element of (0, infinity) and k is a nonnegative integer, is investigated. Some necessary and sufficient as well as sufficient conditions for all solutions of the model to oscillate and some sufficient conditions for all positive solutions of the model to be nonoscillatory and the convergence of nonoscillatory solutions axe derived. Furthermore, the permanence of every positive solution of the model is also showed...
