Consider the higher order neutral differential equation[x(t)-P(t)x(t-τ)] (n) +Ni=1Q i(t)x(t-σ i(t))=0, tt 0with P(t),Q i(t),σ i(t)(i=1,2,…,N) continuous, τ >0 and n is odd. We establish several new sufficient conditions for the oscillation of all solutions. Some of these conditions including generalize and improve the known results one in .
