| Abstract: | The present paper deals with the sufficient and necessary condition of the final positive solutions of non-linear partial-difference equations and first presents the comparison theorem. By means of the comparison theorem, and the oscillation of some non-linear partial difference equations is discussed and some concise conditions and authenticity are given. |
| Keywords: | non-linear partial difference equation continuous variables comparison theorem oscillation final positive solution |
