The Henstock-Kurzweil approach to Young integrals with integrators in BV φ

Boonpogkrong Varayu, Tuan-Seng Chew (2006)

Mathematica Bohemica

Similarity:

In 1938, L. C. Young proved that the Moore-Pollard-Stieltjes integral ∫ a b f d g exists if f ∈ B V φ [ a , b ] , g ∈ B V ψ [ a , b ] and ∑ n = 1 ∞ φ - 1 ( 1 / n ) ψ - 1 ( 1 / n ) < ∞ . In this note we use the Henstock-Kurzweil approach to handle the above integral defined by Young.

A Distance-Based Method for Attribute Reduction in Incomplete Decision Systems

Demetrovics, Janos, Thi, Vu Duc, Giang, Nguyen Long (2013)

Serdica Journal of Computing

Similarity:

There are limitations in recent research undertaken on attribute reduction in incomplete decision systems. In this paper, we propose a distance-based method for attribute reduction in an incomplete decision system. In addition, we prove theoretically that our method is more effective than some other methods.

Numerical boundary layers for hyperbolic systems in 1-D

Claire Chainais-Hillairet, Emmanuel Grenier (2001)

ESAIM: Mathematical Modelling and Numerical Analysis - Modélisation Mathématique et Analyse Numérique

Similarity:

The aim of this paper is to investigate the stability of boundary layers which appear in numerical solutions of hyperbolic systems of conservation laws in one space dimension on regular meshes. We prove stability under a size condition for Lax Friedrichs type schemes and inconditionnal stability in the scalar case. Examples of unstable boundary layers are also given.
