Abstract
Let be a unital positive linear map and let be a positive invertible operator. We prove that there exist partial isometries and such that and hold under some mild operator convex conditions and some positive numbers . Further, we show that if is operator concave, then In addition, we give some counterparts to the asymmetric Choi--Davis inequality and asymmetric Kadison inequality. Our results extend some inequalities due to Bourin--Ricard and Furuta.
