Estimation of -Berezin number and -Berezin norm inequalities via Moore-Penrose inverse
Sumon Ghosh, Swastika Saha Mondal, Sarita Ojha
In this article, we establish the -Berezin number and -Berezin norm inequalities for bounded linear operators on a reproducing kernel Hilbert space using the Moore-Penrose in…
