A weakened version of Davis-Choi-Jensen’s inequality for normalised positive linear maps
Keywords:Operator convex functions, Convex functions, Power function, Logarithmic function, Exponential function.
In this paper we show that the celebrated Davis-Choi-Jensen’s inequality for normalised positive linear maps can be extended in a weakened form for convex functions. A reverse inequality and applications for important instances of convex (concave) functions are also given.
