Desingularization of First Order Linear Difference Systems with Rational Function Coefficients
Desingularization of First Order Linear Difference Systems with Rational Function Coefficients
It is well known that for a first order system of linear difference equations with rational function coefficients, a solution that is holomorphic in some left half plane can be analytically continued to a meromorphic solution in the whole complex plane. The poles stem from the singularities of the rational …
