Classification of five-point differential-difference equations

R. N. Garifullin, R. I. Yamilov, D. Levi

Using the generalized symmetry method, we carry out, up to autonomous point transformations, the classification of integrable equations of a subclass of the autonomous five-point d…

Non-invertible transformations for the classification of differential-difference equations

R. N. Garifullin, R. I. Yamilov, D. Levi

We discuss aspects of the theory of non-invertible transformations which enter in the problem of classification of diffe\-ren\-tial-difference equations and, in particular, the not…
