On Some Numerical Radius Inequalities for Hilbert Space Operators
Mahdi Ghasvareh, Mohsen Erfanian Omidvar
This article is devoted to studying some new numerical radius inequalities for Hilbert space operators. Our analysis enables us to improve an earlier bound of numerical radius due…
A Note Around Operator Bellman Inequality
Shiva Sheybani, Mohsen Erfanian Omidvar, Mahnaz Khanegir
In this paper, we shall give an extension of operator Bellman inequality. This result is estimated via Kantorovich constant.
Sharpening Some Classical Numerical Radius Inequalities
H. R. Moradi, M. E. Omidvar, K. Shebrawi
New upper and lower bounds for the numerical radii of Hilbert space operators are given. Among our results, we prove that if is a hypo…
Complementary Inequalities to Improved AM-GM Inequality
H. R. Moradi, M. E. Omidvar
Following an idea of Lin, we prove that if and be two positive operators such that , then \begin{equation*} {{Φ}^{2}}\left( \frac{A+B}{2…
Unitarily invariant norm inequalities for operators
M. Erfanian Omidvar, M. S. Moslehian, A. Niknam
We present several operator and norm inequalities for Hilbert space operators. In particular, we prove that if , then \[|||A_{1}…
