Some extensions of Berezin number inequalities on operators

Mojtaba Bakherad, Monire Hajmohamadi, Rahmatollah Lashkaripour +1

In this paper, we establish some upper bounds for Berezin number inequalities including of $2 \times 2$ operator matrices and their off-diagonal parts. Among other inequalities, it…

Inequalities involving upper bounds for certain matrix operators

R Lashkaripour, D Foroutannia

In this paper, we considered the problem of finding the upper bound Hausdorff matrix operator from sequence spaces $l_{p} (v)$ (or $d (v, p)$ ) into $l_{p} (w)$ (or $d (w, p)$ ). Also we consi…
