In this paper, we investigate the oscillation of second-order half-linear neutral dynamic equations with distributed deviating arguments of the form (r(t) |zΔ(t)|α-1 z△(t)△ +∫ba q(t,ξ)|x(g(t,ξ))|α-1 x(g(t,ξ))△ξ =0,where r(t)and p(t) are real-valued rd-continuous positive functions definedon T,z(t) =x(t) + p(t)x(τ(t)) and α is a constant with α ≥ 1.By using the generalized Riccati transformation and the inequality technique, we establish some new oscillatory criteria for all solutions to second-order half-linear neutral dynamic equations being oscillatory on the time scale T.In addition, some examples are given to illustrate our main results.
