摘要
The purpose of this paper is to investigate the oscillation of the second-order neutral differential equations of the form (r(t)vertical bar z'(t)vertical bar(alpha-1)z'(t))' + q(t)vertical bar x(sigma(t))vertical bar(alpha-1)x(sigma(t)) = 0, (E) where z(t) = x(t) + p(t)x(tau(t)). The obtained comparison principles essentially simplify the examination of the studied equations. Further, our results extend and improve the results in the literature.
