چکیده

We prove the orthogonality (in the sense of Birkhoff) of the range and the kernel of an important class of elementary operators with respect to the Schatten p-class. 1. Introduction. Let H be a separable infinite-dimensional complex Hilbert space and let B(H) denote the algebra of all bounded operators on H into itself. Given A, B ∈ B(H), we define the generalized derivation δ A,B : B(H) B(H) by δ A,B (X) = AX −XB and the elementary operator derivation ∆ A,B : B(H) B(H)

Some Versions of Anderson’s and Maher’s Inequalities Ii

We are interested in the investigation of the orthogonality (in the sense of Birkhoff) of the range of an elementary operator and its kernel. 1. Introduction. Let H be a separable infinite-dimensional complex Hilbert space and let B(H) denote the algebra of all bounded operators on H into itself. Given A, B ∈ B(H), we define the generalized derivation δ A,B : B(H) B(H) by δ A,B (X) = AX −XB and...

Some Weighted Integral Inequalities for Generalized Conformable Fractional Calculus

In this paper, we have obtained weighted versions of Ostrowski, Čebysev and Grüss type inequalities for conformable fractional integrals which is given by Katugompola. By using the Katugampola definition for conformable calculus, the present study confirms previous findings and contributes additional evidence that provide the bounds for more general functions.

Weak log-majorization inequalities of singular values between normal matrices and their absolute values

‎This paper presents two main results that the singular values of the Hadamard product of normal matrices $A_i$ are weakly log-majorized by the singular values of the Hadamard product of $|A_{i}|$ and the singular values of the sum of normal matrices $A_i$ are weakly log-majorized by the singular values of the sum of $|A_{i}|$‎. ‎Some applications to these inequalities are also given‎. ‎In addi...

Reliability of Pesian versions of activities-specific balance confidence scale and fall efficacy scale-international questionnaires in elderly with stroke

Introduction : Stroke is the leading cause of disability in the elderly population of the world. Fear of falling and balance disruptions are most important of side effects of a stroke leading to mental disorders in some cases. In assessing the balance issues, collecting data about the effect of the disorderon the lifestyle of the patient and perception of the disability by the handicapped seems...
