For a scalar delay generalized logistic equation explicit oscillation conditions are established for all the cases of parameters ฮฑ k , i.e., sublinear, superlinear, and also mixed ones. Coefficients r k t and delays h k t are not assumed to be continuous.

In this paper sufficient conditions for the oscillation of all solutions of the delay difference equation x y x q p x s 0, n s 0, 1, 2, . . . , are established, where the coefficient p itself may be allowed to be oscillatory. We also give an n example to demonstrate the advantage of our results.
