| Abstract: | By employing the concept of frequency measures and unsaturated infinite double sequence,unsaturated solutions are discussed for a class of nonlinear delay partial difference equations with variable coefficients,which may change sigh.Some new criteria of unsaturated solutions are established.Since unsaturated solutions are oscillatory,our results yield oscillation criteria. |

| Keywords: | partial difference equation frequency measure unsaturated solution frequently oscillatory criteria |
