Let D be a Hessenberg matrix and D the closed operator associated to it. In this work, we study the approximation of the resolvent of D by the resolvents of the truncated matrices D n of D: A concept of determinacy is introduced analogous to the one for Jacobi matrices. We apply our results to some
