✦ Synopsis

we construct an important transform to obtain sufficient conditions for the oscillation of all solutions of delay partial difference equations with positive and negative coefficients of the form &+l,n + A m,n+l -A,, +Pmn&-k,n-1 -qmn Am-k~,n-l~ = 0, where m, n = 0, 1,. . , and /c, k', 1', 1 are nonnegative integers, p, q E (0, M), the coefficients {qmn} and {p,,) are sequences of nonnegative real numbers.
