Some inequalities for the Euclidean operator radius of two operators in Hilbert spaces

, 2006
Some sharp bounds for the Euclidean operator radius of two bounded linear operators in Hilbert spaces are given. Their connection with Kittaneh’s recent results which provide sharp upper and lower bounds for the numerical radius of linear operators are ...

A novel method for Milne-type inequalities using proportional Caputo-hybrid operator

Miskolc Mathematical Notes
In mathematics and the applied sciences, fractional calculus is a significant generalization and a very useful tool as it overcomes many limitations of classical analysis.

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

More power vector bounds for operator pairs in Hilbert spaces with applications

Journal of Inequalities and Applications
This paper investigates power vector inequalities for bounded linear operator pairs ( B , C ) $(B,C)$ in a Hilbert space H $\mathcal{H}$ . By leveraging vector inequalities derived by the second author for inner products and norms, we establish various ...

$L^q$ Inequalities and Operator Preserving Inequalities

Analysis in Theory and Applications, 2014
Summary: Let \(\mathbb{P}_n\) be the class of polynomials of degree at most \(n\). \textit{N. A. Rather} and \textit{M. A. Shah} [J. Math. Anal. Appl. 399, No. 1, 422--432 (2013; Zbl 1259.30006)] proved that if \(P\in \mathbb{P}_n\) and \(P(z)\neq 0\) in \(|z|0\) and \(0 \leq ...
