While there is now an extensive literature on the approximation of the eigenvalue problem for compact operators, these theories do not include the classical finite-difference approximation. In the ...

The study of differential-difference equations and boundary value problems occupies an essential niche in applied mathematics, linking the theory of differential operators with discrete translation ...
