In this paper, we present some new oscillation criteria for nonlinear neutral difference equations of the form Δ(b(n)Δ(a(n)Δz(n))) + q(n)xα(σ(n)) = 0 where z(n) = x(n) + p(n)x(τ(n)), α > 0, b(n) > 0, ...
In this article, we study a first order nonlinear delay differential equation x'( t )+ ∑ i=1 m p i ( t ) f i ( x( τ i ( t ) ) )=0, t≥ t 0 , where pi(t) and τi(t) are the functions of nonnegative of ...
