Operator Inequalities and Several Characterizations of the -Mean Transform
Bikram Das, Goutam Biswas, Chandal Nahak
We broaden Buzano-type inequalities to provide novel numerical radius bounds for operators of the type , thereby generalizing the results obtained by Sababheh et al. For the $…

New perspectives on operator radius bounds in weighted frameworks
Bikram Das, Chandal Nahak
By employing the MoorePenrose inverse of a bounded linear operator, we derive several bounds for the numerical radius and operator norms of the sum of operators in semiHilber…
