Poisson结构Jacobi方程的新四维解

New four-dimensional solutions of the Jacobi equations for Poisson structures

Benito Hernández-Bermejo

摘要:

本文刻画了Poisson结构Jacobi方程的一个新的四维反对称解族。因此,以前已知的类型的泊松结构中发现的多样性的物理情况似乎是可获得的特殊情况下,新的家庭的解决方案。此外,可以应用建设性的方法来明确确定这些解决方案的基本属性,如它们的Casimir不变量,辛结构和算法的达布规范形式,这已经被报道只有有限的样本已知的有限维泊松结构。此外,所得结果在相空间中是全局有效的,从而改进了具有局部性质的Darboux定理的适用范围。

英文摘要:

A new four-dimensional family of skew-symmetric solutions of the Jacobi equations for Poisson structures is characterized. As a consequence, previously known types of Poisson structures found in a diversity of physical situations appear to be obtainable as particular cases of the new family of solutions. Additionally, it is possible to apply constructive methods for the explicit determination of fundamental properties of those solutions, such as their Casimir invariants, symplectic structure and the algorithm for the reduction to the Darboux canonical form, which have been reported only for a limited sample of known finite-dimensional Poisson structures. Moreover, the results developed are valid globally in phase space, thus ameliorating the usual scope of Darboux theorem which is of local nature.
