New Estimates for the Numerical Radius
Hamid Reza Moradi, Mohammad Sababheh
In this article, we present new inequalities for the numerical radius of the sum of two Hilbert space operators. These new inequalities will enable us to obtain many generalization…
Buzano, Kreĭn and Cauchy-Schwarz inequalities
Mohammad Sababheh, Hamid Reza Moradi, Zahra Heydarbeygi
The Cauchy-Schwarz, Buzano and Kre\uın inequalities are three inequalities about inner product. The main goal of this article is to present refinements of Buzano and Cauchy-Schwarz…
A convex treatment of numerical radius inequalities
Zahra Heydarbeygi, Mohammad Sababheh, Hamid Reza Moradi
In this article, we prove an inner product inequality for Hilbert space operators. This inequality, then, is utilized to present a general numerical radius inequality using convex…
Singular Values Inequalities for Matrix Means
Mohammed Sababheh, Shigeru Furuichi, Shiva Sheybani +1
In this article, we show multiple inequalities for the singular values of the difference of matrix means. The obtained results refine and complement some well established results i…
Further Subadditive Matrix Inequalities
I. H. Gumus, H. R. Moradi, M. Sababheh
Matrix inequalities that extend certain scalar ones have been at the center of numerous researchers' attention. In this article, we explore the celebrated subadditive inequality fo…
More About Operator Order Preserving
Gholamreza Karamali, Hamid Reza Moradi, Mohammad Sababheh
It is well known that increasing functions do not preserve operator order in general; nor do decreasing functions reverse operator order. However, operator monotone increasing or o…
A new treatment of convex functions
M. Sababheh, S. Furuichi, H. R. Moradi
Convex functions have played a major role in the field of Mathematical inequalities. In this paper, we introduce a new concept related to convexity, which proves better estimates w…
