作为KP tau-函数平方根的BKP tau-函数

BKP tau-functions as square roots of KP tau-functions

Johan van de Leur

摘要:

众所周知,BKP τ函数是某个KP τ函数的平方根,只要我们把偶数KP乘以等于零。本文对所有多项式BKP τ-函数计算其相应的KP“平方”。在多项式的情况下,我们还给出了Alexandov最近的一个结果的表示理论证明,即当所有KdV时间除以2时,KdV τ函数成为BKP τ函数。

英文摘要:

It is well-known that a BKP tau-function is the square root of a certain KP tau-function, provided one puts the even KP times equal to zero. In this paper we compute for all polynomial BKP tau-function its corresponding KP "square". We also give, in the polynomial case, a representation theoretical proof of a recent result by Alexandov, viz. that a KdV tau-function becomes a BKP tau-function when one divides all KdV times by 2.
