Zhang, Bing Gen; Liu, Shu Tang; Cheng, Sui Sun Oscillation of a class of delay partial difference equations. (English) Zbl 0856.39015 J. Difference Equ. Appl. 1, No. 3, 215-226 (1995). The paper deals with a class of partial difference equations of the form \[ u (i + 1,j) + u(i,j + 1) - u(i,j) + p(i,j) u(i - \sigma,j - \tau) = 0, \] where delays \(\sigma\) and \(\tau\) are nonnegative integers. Some oscillation criteria for these equations are obtained.
