Abstract
A real continuous function which is defined on an interval is said to be A-convex if it is convex on the set of self-adjoint elements, with spectra in the interval, in all matrix algebras of the unital C*-algebra A. We give a general formation of Jensen’s inequality for A-convex functions.
