摘要
Using a class of test functions Phi(t, s, T) defined by Sun [13] and a generalized Riccati technique, we establish some new oscillation criteria for the second-order neutral differential equation with distributed deviating argument (r(t)psi(x(t))Z'(t))' + integral(b)(a) q(t, xi)f[x(g(t, xi))]d sigma(xi) = 0, t >= t(0), where Z(t) = x(t)+ p(t)x(t-T). The obtained results are different from most known ones and can be applied to many cases which are not covered by existing results.
