Theorem 1). Our proof is based on the study of operators H, having the form H,(x) = &I + %+*x-‘G+, which allow a direct approach to the convergents (cf.

In mathematical analysis, Pringsheim studied real and complex functions, following the power-series-approach of the Weierstrass school. Pringsheim published numerous works on the subject of complex analysis, with a focus on the summability theory of infinite series and the boundary behavior of analytic functions.
