On Addition Formulae of KP, mKP and BKP Hierarchies
Yoko Shigyo Department of Mathematics, Tsuda College, Kodaira, Tokyo, 187-8577, Japan
Abstract:
In this paper we study the addition formulae of the KP, the mKP and the BKP hierarchies. We prove that the total hierarchies are equivalent to the simplest equations of their addition formulae. In the case of the KP and the mKP hierarchies those results had previously been proved by Noumi, Takasaki and Takebe by way of wave functions. Here we give alternative and direct proofs for the case of the KP and mKP hierarchies. Our method can equally be applied to the BKP hierarchy.
Keywords:
KP hierarchy; modified KP hierarchy; BKP hierarchy.
