摘要
Using general results for (non) oscillation of the second order half-linear differential equation (r(t)Phi(x'))' + c(t)Phi(x) = 0, Phi(x) := |x|(p-2)x, p > 1, (*) we establish new oscillation and nonoscillation criteria for the perturbed half-lineax Euler differential equation (Phi(x'))' + [gamma(p)/t(p) + c(t)] Phi(x) = 0, gamma(p) := (p-1/p)(p).
