Three Inequalities Involving Hyperbolically Trigonometric Functions

, 2003
In the short note, by using mathematical induction and infinite product representations of the cosine function, hyperbolic sine function and hyperbolic cosine function, three inequalities for the cosine function, hyperbolic sine function and hyperbolic ...

Bell's inequalities in the tomographic representation

, 2006
The tomographic approach to quantum mechanics is revisited as a direct tool to investigate violation of Bell-like inequalities. Since quantum tomograms are well defined probability distributions, the tomographic approach is emphasized to be the most ...

Measuring Inequalities in the Distribution of Health Workers: The case of Tanzania. [PDF]

, 2009
The overall human resource shortages and the distributional inequalities in the health workforce in many developing countries are well acknowledged. However, little has been done to measure the degree of inequality systematically.

Some Chen Inequalities for Submanifolds in Trans-Sasakian Manifolds Admitting a Semi-Symmetric Non-Metric Connection

Axioms
In the present article, we study submanifolds tangent to the Reeb vector field in trans-Sasakian manifolds. We prove Chen’s first inequality and the Chen–Ricci inequality, respectively, for such submanifolds in trans-Sasakian manifolds which admit a semi-

On Hilbert-Pachpatte Multiple Integral Inequalities [PDF]

, 2010
We establish some multiple integral Hilbert-Pachpatte-type inequalities. As applications, we get some inverse forms of Pachpatte's inequalities which were established in 1998.

Chen inequalities on warped product Legendrian submanifolds in Kenmotsu space forms and applications

Journal of Inequalities and Applications
In the current work, we study the geometry and topology of warped product Legendrian submanifolds in Kenmotsu space forms F 2 n + 1 ( ϵ ) $\mathbb{F}^{2n+1}(\epsilon )$ and derive the first Chen inequality, including extrinsic invariants such as the mean

Inequalities involving k-Chen invariants for submanifolds of Riemannian product manifolds

Communications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2018
Summary: An optimal inequality involving the scalar curvatures, the mean curvature and the \(k\)-Chen invariant is established for Riemannian submanifolds. Particular cases of this inequality is reported. Furthermore, this inequality is investigated on submanifolds, namely slant, \(F\)-invariant and \(F\)-anti invariant submanifolds of an almost ...

Valid inequalities for the single-item capacitated lot sizing problem with step-wise costs [PDF]

This paper presents a new class of valid inequalities for the single-item capacitated lotsizing problem with step-wise production costs (LS-SW). We first provide a survey of different optimization methods proposed to solve LS-SW.
