Some Inequalities for the Lp-Curvature Image

open access: yesJournal of Inequalities and Applications, 2009
Lutwak introduced the notion of Lp-curvature image and proved an inequality for the volumes of convex body and its Lp-curvature image. In this paper, we first give an monotonic property of Lp-curvature image.

Three Classes of Logarithmically Completely Monotonic Functions Involving Gamma and Psi Functions [PDF]

open access: yes, 2006
By a simple approach, two classes of functions involving Euler’s gamma function and originating from certain problems of traffic flow are proved to be logarithmically completely monotonic and a class of functions involving the psi function is showed ...

On monotone variational inequalities with random data [PDF]

open access: yesJournal of Mathematical Inequalities, 2009
We study monotone variational inequalities with random data and give measurability, existence and uniqueness results in the general framework of a Hilbert space setting. Then we turn to the more structured case where a finite Karhunen-Loeve expansion leads to a separation of the random and the deterministic variables.

Mind the gap: education inequality at the regional level in Portugal, 1986-2005

open access: yesNotas Económicas, 2010
Portugal stands as one of the most unequal countries in terms of income among the developed countries. Over the period 1980-2005, income inequality kept high, fostered mainly by a monotonic increase in earnings inequality.

Lebesgue-p Norm Convergence Analysis of PDα-Type Iterative Learning Control for Fractional-Order Nonlinear Systems

open access: yesDiscrete Dynamics in Nature and Society, 2018
The first-order and second-order PDα-type iterative learning control (ILC) schemes are considered for a class of Caputo-type fractional-order nonlinear systems.

On a Conjecture of Alzer, Berg, and Koumandos

open access: yesMathematics, 2020
In this paper, we find a solution of an open problem posed by Alzer, Berg, and Koumandos: determine ( α , m ) ∈ R + × N such that the function x α | ψ ( m ) ( x ) | is completely monotonic on ( 0 , ∞ ) , where ψ (

Projection Methods for Monotone Variational Inequalities

open access: yesJournal of Mathematical Analysis and Applications, 1999
The authors give some new iterative methods for solving monotone variational inequalities of the form \[ \langle Tu,v- u\rangle\geq 0,\;\forall v\in K, \] where \(K\) is a closed convex set in a Hilbert space \(H\), \(T: K\to H\) is a nonlinear operator.

Is Inflation Regressive or Progressive? Long Run & Short Run Evidence from Pakistan

open access: yesInternational Journal of Management Studies, 2010
The present paper investigates an answer to a key question “is inflation regressive or progressive?” by utilizing time series data from 1971 up to 2005 with reference to Pakistan.

Some inequalities for (p,q) $(p,q)$-mixed volume

open access: yesJournal of Inequalities and Applications, 2018
Lutwak, Yang, and Zhang introduced the concept of (p,q) $(p,q)$-mixed volume whose special cases contain the Lp $L_{p}$-mixed volume and the Lp $L_{p}$-dual mixed volume.
