熵、次熵与初等对称函数

Entropy, subentropy and the elementary symmetric functions

Richard Jozsa, Graeme Mitchison

摘要:

我们利用复围道积分技术研究了熵H和次熵Q作为初等对称多项式的函数,揭示了一系列引人注目的性质。特别是对于这些变量,衍生物的-Q是等于衍生物的H的一个更高的秩序和第一衍生物的H和Q被视为完全单调的功能。因此,exp(-H)和exp(-Q)是无穷可分概率分布的拉普拉斯变换。

英文摘要:

We use complex contour integral techniques to study the entropy H and subentropy Q as functions of the elementary symmetric polynomials, revealing a series of striking properties. In particular for these variables, derivatives of -Q are equal to derivatives of H of one higher order and the first derivatives of H and Q are seen to be completely monotone functions. It then follows that exp (-H) and exp(-Q) are Laplace transforms of infinitely divisible probability distributions.
