Given a sequence $\{x_n\}^\infty_{n=0}$ in a Banach space, it is well known that if there is a sequence $\{t_n\}^\infty_{n=0}$ such that $\|x_{n+1} - x_n\| \leqslant ...
In this paper we use Hilbert space techniques to develop a bound for the error committed in the numerical integration of an analytic function of two complex variables ...
