奇异拟双Hamilton系统的代数特征
An Algebraic Characterization of singular quasi-bi-Hamiltonian systems
摘要:
在本文中,我们证明了一个代数准则,其特征在于奇异的拟双哈密顿结构上的一个一般的,简单的,新的形式化的程序,作者提出的线路。这个过程表明,对于拟双哈密顿系统的定义,Brouzet等人的原始定义中包含的非奇异泊松张量的要求,并不是必须的。此外,它附带表明,一种方法的构造泊松张量在文献中是我们的一个特殊情况。我们提出两个例子。
英文摘要:
In this paper we prove an algebraic criterion which characterizes singular quasi-bi-hamiltonian structures constructed on the lines of a general, simple, new formal procedure proposed by the authors. This procedure shows that for the definition of a quasi-bi-hamiltonian system the requirement of non-singular Poisson tensors, contained in the original definition by Brouzet et al., is not essential. Besides, it is incidentally shown that one method of constructing Poisson tensors available in the literature is a particular case of ours. We present 2 examples.
