HIGHLIGHTS
- who: Alexander V. Mikhailov from the School of Mathematics, University of Leeds, Leeds, UK have published the Article: Perturbative Symmetry Approach for Differential-Difference Equations, in the Journal: (JOURNAL)
- what: The authors propose a new method to tackle the integrability problem for evolutionary of arbitrary order. To formulate integrability conditions which are suitable for any lacunae in the sequence of symmetries, the authors develop here a perturbative symmetry approach for differential- difference equations. The authors demonstrate the power of the method by solving the classification problem for an important family of quasi-linear differential-difference . . .
