here, adomian decomposition method has been used for finding approximateand numerical solutions of nonlinear differential difference equations arising inmathematical physics. two models of special interest in physics, namely, thehybrid nonlinear differential difference equation and relativistic toda couplednonlinear differential-difference equation are chosen to illustrate the validity andthe g...

A systematic investigation to derive nonlinear lattice equations governed by partial difference (P??E) admitting specific Lax representation is presented. Further it shown that for a value of the parameter derived P??E's can be transformed into linear under global transformation. Also demonstrated how higher order ordinary (O?E) or mappings in general and linearizable ones particular from obtai...
