A new collection of tuple operator inequalities
Zameddin I. Ismailov, Pembe Ipek Al, Hamid Reza Moradi +1
In this paper, we present several new bounds for the norm and numerical radius of sums of Hilbert space operators. The obtained bounds form a new collection that enriches our under…
Integral Numerical Radius and Operator Matrix Bounds
Shiva Sheybani, Hamid Reza Moradi, Mohammad Sababheh
We establish new integral inequalities for the numerical radius and the operator norm of bounded linear operators on Hilbert spaces. Our results refine classical triangle-type and…
More inner product bounds with applications
Mohammad Sababheh, Hamid Reza Moradi
The main goal of this paper is to present new bounds for certain inner products in Hilbert spaces, with applications to the numerical radius and the operator norm. The obtained res…
Some inequalities for adjointable operators on Hilbert -modules
Mohammad Sababheh, Hamid Reza Moradi, Qingxiang Xu +1
The main purpose of this paper is, in the general setting of the adjointable operators on Hilbert -modules, to develop two new tools that can be applied to deal with the posit…
