A Summability Factor Theorem for Generalized Absolute Summability

open access: yesReal Analysis Exchange, 2006
In this paper, we establish a summability factor theorem for summability |A, |k as defined in (1) where A is a lower triangular matrix with non-negative entries satisfying certain conditions. Our paper is an extension of the main result of [1] using definition (1) below.

Monotone Hurwitz numbers and the HCIZ integral [PDF]

open access: yes, 2014
In this article, we prove that the complex convergence of the HCIZ free energy is equivalent to the non-vanishing of the HCIZ integral in a neighbourhood of $z=0$.

A note on absolute summability factors

open access: yes, 2002
In this paper, by using an almost increasing and $\delta$-quasi-monotone sequence, a general theorem on $\phi-{\mid{C},\alpha\mid}_k$ summability factors, which generalizes a result of Bor \cite{3} on ${\phi-\mid{C},1\mid}_k$ summability factors, has ...

Weighted $\beta\gamma$-summability of fuzzy functions of order $\theta$

open access: yes, 2016
The concept of weighted $\beta\gamma$ - summability of order $\theta$ in case of fuzzy functions is introduced and classified into ordinary and absolute sense. Several inclusion relations among the sets are investigated.
