On a binary operation for positive operators
Shigeru Furuichi, Hamid Reza Moradi, Cristian Conde +1
M. Lin defined a binary operation for two positive semi-definite matrices in studying certain determinantal inequalities that arise from diffusion tensor imaging. This operation en…
The operator--valued parallelism and norm-parallelism in matrices
M. Mohammadi Gohari, M. Amyari
Let be a Hilbert space, and let be the -algebra of compact operators on . In this paper, we present some characterizations of the n…
Exponential inequalities for positive linear mappings
M. Sababheh, H. R. Moradi, S. Furuichi
In this article, we present exponential-type inequalities for positive linear mappings and Hilbert space operators, by means of convexity and the Mond-Pe\v carić method. The obtain…
On further refinements for Young inequalities
Shigeru Furuichi, Hamid Reza Moradi
In this paper, sharp results on operator Young's inequality are obtained. We first obtain sharp multiplicative refinements and reverses for the operator Young's inequality. Secondl…
New sharp inequalities for operator means
Shigeru Furuichi, Hamid Reza Moradi, Mohammad Sababheh
New sharp multiplicative reverses of the operator means inequalities are presented, with a simple discussion of squaring an operator inequality. As a direct consequence, we extend…
New inequalities for operator concave functions involving positive linear maps
S. Sheybani, M. E. Omidvar, H. R. Moradi
The purpose of this paper is to present some general inequalities for operator concave functions which include some known inequalities as a particular case. Among other things, we…
