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

Published 18 Aug 2023 in math.FA | (2308.09261v1)

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.
