经典力学的代数熵

The algebraic entropy of classical mechanics

Robert I McLachlan, Brett Ryland

摘要:

我们描述了“李代数的经典力学”,模仿李代数产生的动能和势能的一个简单的机械系统相对于规范泊松括号。这是一个多项式分次李代数,一类我们介绍。我们描述了这些李代数,给出了计算经典力学李代数的齐次子空间的维数$c_n$的算法,并确定了它的熵值$\lim_{n\to\infty} c_n^{1/n}$ .它是$1.82542377420108...$,一个与经典力学相关的基本常数。

英文摘要:

We describe the `Lie algebra of classical mechanics', modelled on the Lie algebra generated by kinetic and potential energy of a simple mechanical system with respect to the canonical Poisson bracket. It is a polynomially graded Lie algebra, a class we introduce. We describe these Lie algebras, give an algorithm to calculate the dimensions $c_n$ of the homogeneous subspaces of the Lie algebra of classical mechanics, and determine the value of its entropy $\lim_{n\to\infty} c_n^{1/n}$. It is $1.82542377420108...$, a fundamental constant associated to classical mechanics.
