Abstract

In this paper; we establish the equivalence of the oscillation of the two equations

(x(t)−x(t−r))(n)+p(t)x(t−σ)=0   and   x(n+1)(t)+p(t)rx(t)=0(x(t) - x(t - r))^{(n)} + p(t) x(t - \sigma) = 0 \ \ \ \mathrm {and} \ \ \ x^{(n+1)}(t) + \frac{p(t)}{r} x(t) = 0

where p(t)≥0p(t) ≥ 0 and n≥1n ≥ 1 is odd, from which we obtain some new oscillation conditions and comparison theorems for the first of these equations.
