A function is called matrix monotone if it is matrix monotone for allCited by: that functions that are operator monotone on Iare exactly those functions that are analytic with positive imaginary part in the upper half-plane (Pick functions) and that have an analytic continuation to the lower half-plane acrossI,wherethe continuation is by re ection. This is the content of L owner’s Theorem. Many dif-.

The matrix convexity and the matrix monotony of a real C 1 function f on (0,∞) are characterized in terms of the conditional negative or positive definiteness of the Loewner matrices associated with f, tf(t), and t 2 f(t).Similar characterizations are also obtained for matrix monotone functions Cited by: The hypothesis that the Pick matrix be positive is weaker than the hypothesis that the function f(x) be a monotone matrix function of all orders. This was pointed out to the author by J. Rovnyak. By a theorem of Chandler, the stronger hypothesis implies that the function is Cited by: 4.

A well-known theorem of Loewner [6] then guarantees that these functions are precisely those real functions on the interval J which admit an analytic continuation throughout the upper half .
