Araki, Huzihiro and Hansen, Frank (1998) Jensen's Operator Inequality for Functions of Several Variables. RGMIA research report collection, 2 (6).


The operator convex functions of several variables are characterized in terms of a non-cummutative generalization of Jensen's inequality, extending previous results of F. Hansen and G.K. Pedersen for functions of one variable and of F. Hansen for functions of two variables.
