拟对称函数与KP体系

Quasi-symmetric functions and the KP hierarchy

Aristophanes Dimakis, Folkert Muller-Hoissen

摘要:

拟对称函数出现在求解Kadomtsev-Petviashvili(KP)族的方法中。这还具有一个新的非结合产品的拟对称函数,满足简单的关系,普通产品和外余积。特别是,提供了这个新的产品和外余积,代数的拟对称函数成为一个无穷小双代数。利用这些结果,我们推导出一个序列的身份在代数的拟对称函数,在正式对应的方程的KP层次。

英文摘要:

Quasi-symmetric functions show up in an approach to solve the Kadomtsev-Petviashvili (KP) hierarchy. This moreover features a new nonassociative product of quasi-symmetric functions that satisfies simple relations with the ordinary product and the outer coproduct. In particular, supplied with this new product and the outer coproduct, the algebra of quasi-symmetric functions becomes an infinitesimal bialgebra. Using these results we derive a sequence of identities in the algebra of quasi-symmetric functions that are in formal correspondence with the equations of the KP hierarchy.
