Virasoro type algebraic structure hidden in the constrained discrete KP hierarchy
Maohua Li, Chuanzhong Li, Keilei Tian +2
In this paper, we construct the additional symmetries of one-component constrained discrete KP (cdKP) hierarchy, and then prove that the algebraic structure of the symmetry flows i…
