Heat equation and convolution inequalities [PDF]
arXiv, 2013 It is known that many classical inequalities linked to convolutions can be obtained by looking at the monotonicity in time of convolutions of powers of solutions to the heat equation, provided that both the exponents and the coefficients of diffusions are suitably chosen and related.

A Rethink on Measuring Health Inequalities Using the Gini Coefficient [PDF]
Objective- We show that a standardized Gini coefficient that takes into account the feasible range of health inequality for a given health attribute is a better instrument than the normal Gini coefficient for quantifying inter-individual health ...

Food Tastes in the United States: Convergence or Divergence?
Agribusiness, EarlyView.ABSTRACT This study investigates how food consumption tastes have changed in recent decades across the United States. Using NielsenIQ data for over 77 million transactions, there is evidence of divergence in food tastes across regions from 2007 to 2016 and across households of different income, education, and race/ethnicity groups.

Measures of Poverty and Inequality: A Reference Paper [PDF]
This paper discusses various measures of poverty and inequality found in the literature. Inequality measures discussed include the range, the variance, the coefficient of variation, the standard deviation of logarithms, the Gini coefficient, Theil's ...

Coefficient inequalities for a subclass of starlike functions
Journal of Mathematical Analysis and Applications, 1985 AbstractA function f(z) = z − ∑∞n = 2 anzn, an ⩾ 0, analytic and univalent in the unit disk, is said to be in the family T∗(a, b), a real and b ⩾ 0, if ¦(zf′f) − a¦ ⩽ b for all z in the unit disk. A complete characterization is found for T∗(a, b) when a ⩾ 1.

Improved Vietoris Sine Inequalities for Non-Monotone, Non-Decaying Coefficients [PDF]
arXiv, 2015 Recently the author established an improvement of the classical Vietoris sine inequality to include sine polynomials with non-monotone coefficients. In this paper two further improvements are presented admitting sine polynomials with non-monotone and non-decaying coefficients. The extremal sums of the two results have the coefficient sequences {2a,

On the Decomposition of the Gini Coefficient: an Exact Approach, with an Illustration Using Cameroonian Data [PDF]
Decomposing inequality indices across household groups or income sources is useful in estimating the contribution of each component to total inequality.
