We present an extension of a family of second-order integrable mappings to the case where the variables do not commute. In every case we introduce a commutation rule which is consistent with the mapping evolution. Through the proper ordering of variables we ensure the existence of an invariant in the...

This paper shows that several integrable lattices can be transformed into coupled biliear differential-difference equations by introducing auxiliary variables.
