摘要
本文利用Virasoro型的对称代数的两种具体的实现获得了各种2+1维具有无穷维Kac-Moody-Virasoro型李代数的不变方程。一些熟知的高维可积模型例如KP方程也被给出。
In this paper,using two,explicit realizations of the Virasoro type symmetry algebra,we obtained various 2+l-dimensional invariant equations which possess the infinitely dimensional Kac-MoodyVirasoro type Lie symmetry algebra.Some well-known higher dimensional integrable models such as K P equation are also given.Abstract:In this paper,using two,explicit realizations of the Virasoro type symmetry gebra,we obtained various 2+l-dimensional invariant equations which possess the infinitely dimensional Kac-MoodyVirasoro type Lie symmetry algebra.Some well-known higher dimensional integrable models such as K P equation are also given.
