本文证明了关于正半定矩阵的混合判判式的若干不等式,以及关于紧凸集的混合体积的若干不等式。此外,我们讨论了后者如何与凸体类上的信息泛函的单调性相关,凸体类是经典费雪信息的几何类比。
In this note we prove certain inequalities for mixed discriminants of positive semi-definite matrices, and mixed volumes of compact convex sets in ℝn. Moreover, we discuss how the latter are related to the monotonicity of an information functional on the class of convex bodies, which is a geometric analogue of the classical Fisher information.
