Jacobi和Plucker之后的Poisson括号

Poisson brackets after Jacobi and Plucker

Pantelis A. Damianou

摘要:

我们构造了一个解为Jacobi椭圆函数的三维系统的辛实现和双哈密顿公式。我们推广这个系统和相关的泊松括号更高的维度。这些更一般的系统是由射影空间中的直线参数化的。对于这些秩为2的Poisson括号,Jacobi恒等式仅在Pl”ucker关系成立时才满足。其中两个泊松括号是相容的,当且仅当射影空间中相应的直线相交。我们提出了几个这样的系统的例子。

英文摘要:

We construct a symplectic realization and a bi-hamiltonian formulation of a 3-dimensional system whose solution are the Jacobi elliptic functions. We generalize this system and the related Poisson brackets to higher dimensions. These more general systems are parametrized by lines in projective space. For these rank 2 Poisson brackets the Jacobi identity is satisfied only when the Pl\" ucker relations hold. Two of these Poisson brackets are compatible if and only if the corresponding lines in projective space intersect. We present several examples of such systems.
