JOURNAL OF DIFFERENCE EQUATIONS AND APPLICATIONS
A space of boundary values is constructed for a minimal symmetric second-order difference operator with matrix coefficients on the whole-line. A description of all maximal dissipative, maximal accretive, self-adjoint and other extensions of such operators is given in terms of boundary conditions at +/-.
