Chen inequalities for statistical submersions between statistical manifolds

open access: yesInternational Journal of Geometric Methods in Modern Physics, 2021
We study statistical submersions between statistical manifolds. In particular, we establish Chen–Ricci inequalities of statistical submersions between statistical manifolds and a [Formula: see text] Chen-type inequality for statistical submersions. Some applications are also given.

Some determinantal inequalities for Hadamard and Fan products of matrices

open access: yesJournal of Inequalities and Applications, 2016
In this note, we generalize some determinantal inequalities which are due to Lynn (Proc. Camb. Philos. 60:425-431, 1964), Chen (Linear Algebra Appl. 368:99-106, 2003) and Ando (Linear Multilinear Algebra 8:291-316, 1980).

Sharp Cusa and Becker-Stark inequalities [PDF]

open access: yes, 2011
We determine the best possible constants θ,ϑ,α and β such that the inequalities ((2+cosx)/3)^θ < sinx/x < ((2+cosx)/3)^ϑ and ((π^2)/(π^2-4×^2))^α < tan×/× < ((π^2)/(π^2-4×^2))^β are valid for 0 < × < π/2.

The Best Bounds in Gautschi-Kershaw Inequalities

open access: yes, 2005
By employing the convolution theorem of Laplace transforms, some asymptotic formulas and integral representations of the gamma, psi and polygamma functions, and other analytic techniques, this note provides an alternative proof of a monotonicity and ...

A New Implementable Prediction-Correction Method for Monotone Variational Inequalities with Separable Structure

open access: yesAbstract and Applied Analysis, 2013
The monotone variational inequalities capture various concrete applications arising in many areas. In this paper, we develop a new prediction-correction method for monotone variational inequalities with separable structure.

Applications of differential equations to characterize the base of warped product submanifolds of cosymplectic space forms

open access: yesJournal of Inequalities and Applications, 2020
In the present, we first obtain Chen–Ricci inequality for C-totally real warped product submanifolds in cosymplectic space forms. Then, we focus on characterizing spheres and Euclidean spaces, by using the Bochner formula and a second-order ordinary ...

Chen-Type Inequality for Generic Submanifolds of Quaternionic Space Form and Its Application

open access: yesJournal of New Theory
In 1993, the theory of Chen invariants started when Chen wrote basic inequalities for submanifolds in space forms. This inequality is called Chen’s first inequality. Afterward, many geometers studied many papers dealing with this new inequality.

A Set of Mathematical Constants Arising Naturally in the Theory of the Multiple Gamma Functions

open access: yesAbstract and Applied Analysis, 2012
We introduce a set of mathematical constants which is involved naturally in the theory of multiple Gamma functions. Then we present general asymptotic inequalities for these constants whose special cases are seen to contain all results very recently ...
