Abstract
Through the generalized Wronskian technique we derive the whole class of nonlinear differential difference equations associated with the discrete analog of the matrix Schrödinger spectral problem. For such equations we briefly discuss soliton solutions, continuum limit, and Bäcklund transformations.Keywords
