A-numerical radius inequalities and a-translatable radii of semi-Hilbert space operators


Messaoud Guesba, Pintu Bhunia, Kallol Paul




We develop A-numerical radius inequalities of the product and the commutator of semi-Hilbert space operators using the notion of A-numerical radius distance and A-seminorm distance. Further, we introduce a pair of translatable radii of semi-Hilbert space operators in the direction of another operator and obtain related inequalities which generalize the relevant inequalities studied in the setting of Hilbert space.
