多辛流形的约化

Reduction of polysymplectic manifolds

Juan Carlos Marrero, Narciso Román-Roy, Modesto Salgado, Silvia Vilariño

摘要:

本文的目的是将辛流形的经典Marsden-Weinstein约化过程推广到多辛流形,以得到具有多辛结构的商流形.这种推广使我们能够减少多辛哈密顿系统的对称性,如那些出现在某些类型的经典场论。作为这一技巧的应用,得到了一个类似于多辛流形上的Kirillov-Kostant-Souriau定理的结果,并分析了其它一些数学例子。我们的程序纠正了以前关于这个问题的论文[29,50]中的一些错误和不准确之处。

英文摘要:

The aim of this paper is to generalize the classical Marsden-Weinstein reduction procedure for symplectic manifolds to polysymplectic manifolds in order to obtain quotient manifolds which in- herit the polysymplectic structure. This generalization allows us to reduce polysymplectic Hamiltonian systems with symmetries, such as those appearing in certain kinds of classical field theories. As an application of this technique, an analogous to the Kirillov-Kostant-Souriau theorem for polysymplectic manifolds is obtained and some other mathematical examples are also analyzed. Our procedure corrects some mistakes and inaccuracies in previous papers [29, 50] on this subject.
