摘 要: |
In this lecture, I will first give a brief review of the (l-l')-th modified KP (mKP) hierarchy, also known as the discrete KP hierarchy, which can be viewed as the orbits of the Darboux transformations. In particular, the 1st mKP hierarchy is just the mKP hierarchy of the Kupershmidt–Kiso version. BKP and modified BKP hierarchies can be viewed as the sub-hierarchies of the 1st mKP hierarchy. Next, the major content of this lecture is devoted to the super extension of the 1st mKP hierarchy in the Kac-van de Leur construction. After introducing some backgrounds in the super extension of KP theory, we construct the corresponding bilinear equations, rewrite them into the super Hirota bilinear forms, and discuss the Darboux transformations in terms of the superfermions. At last, the bilinear equations by introducing the super wave functions are given, which is hoped to be helpful in the derivation of the Lax structures for the super 1st mKP hierarchy. |
