摘要
Oscillation criteria are established for second order nonlinear neutral differential equations with deviating arguments of the form r (t) Psi(x(t))vertical bar(alpha-1) z' (t) + integral(b)(a) q(t,epsilon) f(x(g(t,Psi(g(t,Psi))do (epsilon) = 0,t >= to, where alpha > 0 and z (t) = x t) + p (t) x (t - T). Our results improve and extend some known results in the literature. Some illustrating examples are also provided to show the importance of our results.
