Inequality in Latin America

, 2004
With the exception of Sub-Saharan Africa, Latin America and the Caribbean has been one of the regions of the world with the greatest inequality. This report explores why the region suffers from such persistent

A Nonlinear Generalizations of Dynamic Inequalities on Time Scales

Ratio Mathematica
Considering the distinctive generalization of the Gronwall-Bellman inequality, in this paper we innovates new dynamical inequalities on time scale. These inequalities will be acted a profound tools for studying qualitative properties such as uniqueness ...

Impulsive Problems for Fractional Differential Equations with Nonlocal Boundary Value Conditions

Abstract and Applied Analysis, 2014
We investigate the nonlocal boundary value problems of impulsive fractional differential equations. By Banach’s contraction mapping principle, Schaefer’s fixed point theorem, and the nonlinear alternative of Leray-Schauder type, some related new ...

Education, Inequality and Income Inequality [PDF]

In this paper we propose to measure inequality of educational achievements by constructing a Gini index on educational attainments. We then use the proposed measure to analyse the relationship between inequality in incomes and educational achievements ...

On the long-time behavior of the continuous and discrete solutions of a nonlocal Cahn–Hilliard type inpainting model

International audienceIn this paper, we study the analytical and numerical long-time stability of a nonlocal Cahn-Hilliard model with a fidelity term for image inpainting introduced in our previous work. First, we establish the uniform boundedness of the

Inequality of opportunity and growth [PDF]

Theoretical and empirical studies exploring the effects of income inequality upon growth reach a disappointing inconclusive result. This paper postulates that one reason for this ambiguity is that income inequality is actually a composite measure of at ...
