摘要
In this paper, we consider the partial difference equation with continuous variables of the form p(1)z (x + a, y + b) + p(2)z (x + a, y) + p(3)z (x, y + b) - p(4)z (x, y) + P (x, y) z (x - tau, y - sigma) = 0, where P is an element of C(R+ x R+, R+ - {0}), a, b, tau, sigma are real numbers and p(i) (i = 1, 2, 3, 4) are nonnegative constants. Some sufficient conditions for all solutions of this equation to be oscillatory are obtained. (C) 2000 Elsevier Science Ltd. All rights reserved.
