Abstract

In this paper some new oscillation criteria are obtained for the first order nonlinear differential equation $${ x′ (t) = \sum^{n}_{i=1} p_i(t)f_i(x(σ_0(t)), . . . , x(σ_m(t))), \ \ \ \ \ t ≥ α }$$ with advanced arguments, where ${n ≥ 1, \ m ≥ 1 }$are integers, ${ p_i(t) ≥ 0, \  σ_j (t) ≥ t }$ and ${ x_0f_i(x_0, . . . , x_m) > 0 }$ for ${ t ≥ α, \ x_0x_j > 0, \ \  i = 1, . . . , n, \ \ j = 0, . . . , m.}$
