In this paper, we consider the following higher-order neutral functional differential equations with positive and negative coefficients: -& [z(t) + cx (t -T)l + (-1) \*+l [P(t)?2 (t -CT) -Q(t)2 (t -a)] = 0, t 2 to, where n > 1 is an integer, c E R, ~,o,6 E W+, and P,Q E C([to,m),W+), IR+ = [O ,oo).
obtain some new results for oscillation of all solutions of the neutral differential equation with positive and negative coefficients i [y(t) -R(Mt -r)l + P(Mt -7) -Q(Mt -0) = 0, where P,Q, R E C([to, co),R), r E (O,m), and r,(~ E [O,w). These new results are obtained by establishing and using some
