WebThe Vivanti–Pringsheim theorem is a mathematical statement in complex analysis, that determines a specific singularity for a function described by certain type of power series. … WebSeveral aspects of the convergence of a double series in the sense of Pringsheim are considered in analogy with some well-known results for single series. They include various tests for absolute convergence and also criteria for convergence of the Cauchy product. Some errors in the works of earlier authors are corrected.

WebTaylor's theorem states that any function satisfying certain conditions may be represented by a Taylor series, Taylor's theorem (without the remainder term) was devised by Taylor in 1712 and published in 1715, although Gregory had actually obtained this result nearly 40 years earlier. In fact, Gregory wrote to John Collins, secretary of the Royal Society, on … WebAug 1, 1982 · In this paper we prove a theorem which is an extension of a wellknown theorem of Pringsheim and, in particular, guarantees the convergence of (1) under the … WebIn this paper, we prove a convergence theorem for continued fractions of type (1) which is closely related to a theorem of Pringsheim (cf. 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. glitched alphabet
