##### 1. Some improvements of numerical radius inequalities via Specht’s ratio

*Volume 09, Issue 03 , Summer 2020, , Pages 221-230*

#####
**Abstract **

We obtain some inequalities related to the powers of numerical radius inequalities of Hilbert space operators. Some results that employ the Hermite-Hadamard inequality for vectors in normed linear spaces are also obtained. We improve and generalize some inequalities with respect to ...

##### 2. The solutions to some operator equations in Hilbert $C^*$-module

*Volume 04, Issue 01 , Winter 2015, , Pages 35-42*

#####
**Abstract **

In this paper, we state some results on product of operators with closed ranges and we solve the operator equation $TXS^*-SX^*T^*= A$ in the general setting of the adjointable operators between Hilbert $C^*$-modules, when $TS = 1$. Furthermore, by using some block operator matrix techniques, ...
