Refinements of generalized Euclidean operator radius inequalities of $2$-tuple operators

Kallol Paul

Abstract


We develop several upper and lower bounds for the $A$-Euclidean operator radius of $2$-tuple operators admitting $A$-adjoint, and show that they refine the earlier related bounds. As an application of the bounds developed here, we obtain  sharper $A$-numerical radius bounds.
