Invariant and Absolute Invariant Means of Double Sequences

Journal of Function Spaces and Applications, 2012
We examine some properties of the invariant mean, define the concepts of strong σ-convergence and absolute σ-convergence for double sequences, and determine the associated sublinear functionals.

On the Pringsheim convergence of double series; pp. 108–121 [PDF]

Proceedings of the Estonian Academy of Sciences, 2009
Several 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

Performance Persistence and Gamma Convergence in Absolute Return Funds in Poland Over the Period 2011-2018

Nauki o Finansach, 2020
This article attempts to analyse the investment performance of absolute return funds in 2011-2018 in Poland from the point of view of their performance persistence and the occurrence of gamma convergence. Two research hypotheses were verified.

Development of a New Multi-step Iteration Scheme for Solving Non-Linear Models with Complex Polynomiography

Complexity, 2022
The appearance of nonlinear equations in science, engineering, economics, and medicine cannot be denied. Solving such equations requires numerical methods having higher-order convergence with cost-effectiveness, for the equations do not have exact ...

Revisiting the Relationship between β and σ Convergence [PDF]

Pakistan Journal of Applied Economics, 2016
The paper questions the widely held assumptions about the relationship between absolute β-convergence and σ-convergence in the existing literature which states that β-convergence is a necessary condition for σ-convergence.

Absolute and Conditional Convergence: Its Speed for Selected Countries for 1961--2001 [PDF]

The study gives the theoretical justification for the per capita growth equations using Solovian model(1956) and its factor accumulation assumptions. The different forms of the per capita growth equation is used to test for 'absolute convergence' and ...

Convergence-Enhanced and ANN-Accelerated Solvers for Absolute Value Problems

Axioms
Absolute value problems of the form Ax−|x|=b, where x∈Rn is the unknown vector, b∈Rn is a given vector, and A∈Rn×n is a matrix, arise in a wide range of scientific and engineering applications.

Convergence Among the U.S. States: Absolute, Conditional, or Club? [PDF]

This paper attempts to ascertain which of the convergence hypotheses – absolute, conditional, or club – best describes the economic development of the U.S. states since 1950.

Convergence across Russian regions: a spatial econometrics approach [PDF]

, 2007
This paper analyses the process of convergence across the regions of Russia using spatial econometrics tools in addition to the traditional β-convergence techniques as derived from the neoclassical theoretical setting. The spatial component appears to be

Convergence and Long Run Uncertainty [PDF]

In this paper the neoclassical convergence hypothesis is tested for the thirteen regions of Chile using crosssection and time-series techniques. Cross-section analysis in combination with a Bayesian Modeling Averaging strategy supports the convergence ...
