Is every absolutely convergent series convergent?

The Mathematical Gazette, 1977
There are various ways of introducing a discussion of the completeness of the system of real numbers. In this article we take the unusual approach suggested by the provocative question of the title.In any elementary treatment of the convergence of sequences and series, a discussion of series of positive and negative terms will lead to the theorem that ...

On the absolute convergence of multiple fourier series

Acta Mathematica Hungarica, 2007
Let \(f:\mathbb R^N\to \mathbb C\) be a periodic function with period \(2\pi\) in each variable. The authors obtain sufficient conditions for the absolute convergence of the multiple Fourier series of the function \(f\) in terms of moduli of continuity, of bounded variation in the sense of Vitali or Hardy and Krause, and of the mixed partial derivative

Integral Operators and Absolute Convergence Systems

Siberian Mathematical Journal, 2002
The author uses special integral operators (Carleman operators) to establish several special properties of absolute convergence systems for \(l_2\). The following notion of an absolute convergence system is used: a sequence \(\{g_n\}\subset M\) (\(M = M(X,\mu)\) denotes the space of all \(\mu\)-measurable \(\mu\)-a.e. finite functions on \(X\), where \(

Absolute almost convergence and absolute almost summability

1987
Let \(A=(a_{nk})\) be an infinite matrix of real or complex numbers and let \(Ax=(A_ n(x))\) if \(A_ n(x)=\sum_{k}a_{nk}x_ k\) converges for each n, where \(x=(x_ n)\) is a given sequence. Suppose \((p_ n)\) is a positive bounded sequence of real numbers, the author defines \(| A,p| =\{x:\sum_{n}| A_ n(x)|^{p_ n}
