Recursion operators for KP, mKP and Harry-Dym Hierarchies
Jipeng Cheng, Lihong Wang, Jingsong He
In this paper, we give a unified construction of the recursion operators from the Lax representation for three integrable hierarchies: Kadomtsev-Petviashvili (KP), modified Kadomts…

Additional symmetries of constrained CKP and BKP hierarchies
Kelei Tian, Jingsong He, Jipeng Cheng +1
The additional symmetries of the constrained CKP (cCKP) and BKP (cBKP) hierarchies are given by their actions on the Lax operators, and their actions on the eigenfunction and adjoi…

The "Ghost" Symmetry of the BKP hierarchy
Jipeng Cheng, Jingsong He, Sen Hu
In this paper, we systematically develop the "ghost" symmetry of the BKP hierarchy through its actions on the Lax operator , the eigenfunctions and the function. In this pro…
