%0 Journal Article %T Frequent Oscillatory Behavior of Delay Partial Difference Equations with Positive and Negative Coefficients %A Xu LiHua %A Yang Jun %J Advances in Difference Equations %D 2010 %I Springer %X This paper is concerned with a class of nonlinear delay partial difference equations with positive and negative coefficients, which also contains forcing terms. By making use of frequency measures, some new oscillatory criteria are established. %U http://www.advancesindifferenceequations.com/content/2010/606149
