By using Riccati transformation techniques we will establish some oscillation criteria for the second order neutral delay difference equation ∆ [p(n) (∆ (x(n) + q(n)x(n− τ) + h(n)x(n− σ)))γ ] +f(n,… (More)

denotes the greatest integer function, and x−1, x0 are given real numbers. Since 1980’s differential equations with piecewise constant arguments have attracted great deal of attention of researchers… (More)

was initiated in ([13],[30]) where h (t) = [t] , [t− n] , [t+ n] , etc. These types of equations have been intensively investigated for twenty five years. Systems described byDEPCA exist in a large… (More)
