含伪相系统多维Poisson括号的平均

The averaging of multi-dimensional Poisson brackets for systems having pseudo-phases

A. Ya. Maltsev

摘要:

我们认为在伪相位的存在下的Whitham方法的哈密顿制定的功能。正如我们所展示的,在这种情况下,可以提出一个类似的过程中平均的泊松括号减少第一积分的数量。平均括号给出了相应的Whitham系统的泊松结构,其形式类似于存在普通相位时产生的结构。

英文摘要:

We consider features of the Hamiltonian formulation of the Whitham method in the presence of pseudo-phases. As we show, an analog of the procedure of averaging of the Poisson bracket with the reduced number of the first integrals can be suggested in this case. The averaged bracket gives a Poisson structure for the corresponding Whitham system having the form similar to the structures arising in the presence of ordinary phases.
