COVID-19 and digital inequalities: Reciprocal impacts and mitigation strategies
With more than three billion people in isolation, the status of digital spaces is switching from an amenity to a
necessity, as they become not only the main way to access information and services, but also one of the ...
Improved Poincaré inequalities in fractional Sobolev spaces
(Suomalainen Tiedeakatemia, 2018-03)
We obtain improved fractional Poincaré and Sobolev-Poincaré inequalities including powers of the distance to the boundary in bounded John, s-John, and Hölder-α domains, and discuss their optimality.
On the Search for weighted inequalities for Operators related to the Ornstein-Uhlenbeck Semigroup
(Springer, 2000-12)
In this paper,for each given p, 1 < p < ∞, we characterize the weights v for which the centered maximal function with respect to the gaussian measure and the Ornstein-Uhlenbeck maximal operator are well defined for every ...
Higher order turän inequalities
(1998-12-01)
The celebrated Turân inequalities P 2 n(x)-P n-x(x)P n+1(x) ≥ 0, x ε[-1,1], n ≥ 1, where P n(x) denotes the Legendre polynomial of degree n, are extended to inequalities for sums of products of four classical orthogonal ...
Human capital and the recent fall of earnings inequality in Brazil
(Sociedade Brasileira de Econometria, 2011-12-02)
Earnings inequality has started to fall in Brazil in recent years, after remaining very high for decades. We describe this decline using a flexible decomposition technique and assess the contributions of education and ...
Order Relations, Convexities, and Jensen's Integral Inequalities in Interval and Fuzzy Spaces
(Springer, 2018-01-01)
This study presents new interval and fuzzy versions of the Jensen's integral inequality, which extend the classical Jensen's integral inequality for real-valued functions, using Aumann and Kaleva integrals. The inequalities ...
