Additive Refinements and Reverses of Young's Operator Inequality Via a Result of Cartwright and Field

open access: yesUniversal Journal of Mathematics and Applications, 2021
In this paper we obtain some new additive refinements and reverses of Young's operator inequality via a result of Cartwright and Field. Comparison with other additive Young's type inequalities are also provided.

Computation of π Using Arithmetic-Geometric Mean [PDF]

open access: yesMathematics of Computation, 1976
A new formula for π \pi is derived. It is a direct consequence of Gauss’ arithmetic-geometric mean, the traditional method for calculating elliptic integrals, and of Legendre’s relation for elliptic integrals. The error analysis shows that its rapid convergence doubles the number of significant digits after each step.

Sharp two-parameter bounds for the identric mean

open access: yesJournal of Inequalities and Applications, 2018
For t∈[0,1/2] $t\in [0,1/2]$ and s≥1 $s\ge 1$, we consider the two-parameter family of means Qt,s(a,b)=Gs(ta+(1−t)b,(1−t)a+tb)A1−s(a,b), $$ Q_{t,s}(a,b)=G^{s}\bigl(ta+(1-t)b,(1-t)a+tb\bigr)A^{1-s}(a,b), $$ where A and G denote the arithmetic and ...

Inequalities between Arithmetic‐Geometric, Gini, and Toader Means [PDF]

open access: yesAbstract and Applied Analysis, 2011
We find the greatest values p1, p2 and least values q1, q2 such that the double inequalities and hold for all a, b > 0 with a ≠ b and present some new bounds for the complete elliptic integrals. Here M(a, b), T(a, b), and Sp(a, b) are the arithmetic‐geometric, Toader, and pth Gini means of two positive numbers a and b, respectively.

Some picture fuzzy mean operators and their applications in decision-making [PDF]

open access: yesJournal of Fuzzy Extension and Applications, 2022
Picture fuzzy set is the generalization of fuzzy set and intuitionistic fuzzy set. It is useful for handling uncertainty by considering the positive membership, neutral membership and negative membership degrees independently for each element of a ...

Geometric Mean Curvature Lines on Surfaces Immersed in R3 [PDF]

open access: yes, 2002
Here are studied pairs of transversal foliations with singularities, defined on the Elliptic region (where the Gaussian curvature $\mathcal K$ is positive) of an oriented surface immersed in $\mathbb R^3$.

Optimal two-parameter geometric and arithmetic mean bounds for the Sándor–Yang mean

open access: yesJournal of Inequalities and Applications, 2019
In the article, we provide the sharp bounds for the Sándor–Yang mean in terms of certain families of the two-parameter geometric and arithmetic mean and the one-parameter geometric and harmonic means.
