离散串的Poisson族

Poisson Hierarchy of Discrete Strings

Theodora Ioannidou, Antti Niemi

摘要:

研究了三维欧氏空间中离散弦的Poisson几何。为此,将Frenet标架转换为旋量表示,离散的旋量Frenet方程被解释为传递矩阵形式主义,泊松括号被引入旋量分量。然后一般化的建设,在一个自相似的方式,到一个无限层次的泊松代数。作为一个例子,经典的Virasoro(维特)代数,确定沿连续字符串的重参数化仿射,被确定为一个特定的子代数,在离散字符串泊松代数的层次。

英文摘要:

The Poisson geometry of a discrete string in three dimensional Euclidean space is investigated. For this the Frenet frames are converted into a spinorial representation, the discrete spinor Frenet equa- tion is interpreted in terms of a transfer matrix formalism, and Poisson brackets are introduced in terms of the spinor components. The construction is then generalised, in a self-similar manner, into an infinite hierarchy of Poisson algebras. As an example, the classical Virasoro (Witt) algebra that determines reparametrisation diffeomorphism along a continuous string, is identified as a particular sub-algebra, in the hierarchy of the discrete string Poisson algebra.
