摘要：We obtain the Lie symmetries of two (2+1)-dimensional differential-difference equations based on the extended Harrison and Estabrook's geometric approach that is extended from the continuous differential equations to the differential-difference equations. Moreover, it is shown that both of the two equations possess a Kac-Moody-Virasoro symmetry algebra.
