OSCILLATION THEOREMS FOR FORCED NEUTRAL DIFFERENCE-EQUATIONS

[摘要] Some oscillation criteria are established for forced neutral difference equations of the form DELTA(x(n) + px(n + deltak) - q(n) f(x(taun)) = F(n) and DELTA2(x(n) + px(n+deltak)) + q(n) f(x(taun)) = F(n). The results remain valid even when F(n) = 0. (C) 1994 Academic Press, Inc.
