On the Cauchy--Rassias Inequality and Linear n-Inner Product Preserving Mappings

open access: yes, 2005
We prove the Cauchy-Rassias stability of linear n-inner product preserving mappings in $n$-inner product Banach spaces. We apply the Cauchy-Rassias inequality that plays an influencial role in the subject of functional equations.

Gradient estimates and the fundamental solution for higher-order elliptic systems with lower-order terms

open access: yesAdvanced Nonlinear Studies, 2023
We establish the Caccioppoli inequality, a reverse Hölder inequality in the spirit of the classic estimate of Meyers, and construct the fundamental solution for linear elliptic differential equations of order 2m2m with certain lower order terms.

Exponential stability of Cohen-Grossberg neural networks with multiple time-varying delays and distributed delays

open access: yesAIMS Mathematics, 2023
Maybe because Cohen-Grossberg neural networks with multiple time-varying delays and distributed delays cannot be converted into the vector-matrix forms, the stability results of such networks are relatively few and the stability conditions in the linear ...

Generalizations of the Kantorovich and Wielandt Inequalities with Applications to Statistics

open access: yesMathematics
By utilizing the properties of positive definite matrices, mathematical expectations, and positive linear functionals in matrix space, the Kantorovich inequality and Wielandt inequality for positive definite matrices and random variables are obtained ...

Analysis of Relationship between Per Capita Income Growth, Household Debt and Income Inequality (Case Study: Iranian Provinces) [PDF]

open access: yesFaslnāmah-i Pizhūhish/Nāmah-i Iqtisādī, 2018
After world recession in 2008, many papers focused on non-linear relationship between debt and growth. Based on traditional theories, a medium level of increase in debt can improve welfare and economic growth, but a high level of it damages the economy ...

Linear entropy and Bell inequalities [PDF]

open access: yesPhysical Review A, 2000
For mixed states of a pair of spin-1/2 particles, the positivity of the sum of the conditional linear entropies is a sufficient condition for the nonviolation of the Bell-CHSH (Clauser-Horne-Shimony-Holt) inequalities.

Stability Analysis of Systems with Interval Time-Varying Delays via a New Integral Inequality

open access: yesComplexity, 2020
This paper focuses on delay-dependent stability analysis for systems with interval time-varying delays. Based on a new integral inequality and a generalized reciprocally convex combination matrix inequality, a new delay-dependent stability criterion is ...

The Relationship Between Annual GDP Growth and Income Inequality: Developed and Undeveloped Countries [PDF]

open access: yes, 2017
The hypothesis is that there exists a linear relationship between income inequality and annual GDP growth rate. When the GDP growth rate decreases, the income inequality also decreases.

On the effectiveness of projection methods for convex feasibility problems with linear inequality constraints [PDF]

open access: yesComputational optimization and applications, 2009
The effectiveness of projection methods for solving systems of linear inequalities is investigated. It is shown that they often have a computational advantage over alternatives that have been proposed for solving the same problem and that this makes them

Likelihood Ratio Tests in Linear Models with Linear Inequality Restrictions on Regression Coefficients

open access: yesRevstat Statistical Journal, 2015
This paper develops statistical inference in linear models, dealing with the theory of maximum likelihood estimates and likelihood ratio tests under some linear inequality restrictions on the regression coefficients. The results are widely applicable to
