Chuanzhong Li, Jingsong He Department of Mathematics, Ningbo University, Ningbo, China
Abstract:
We construct Virasoro-type additional symmetries of a kind of constrained multicomponent Kadomtsev–Petviashvili (KP) hierarchy and obtain the Virasoro flow equation for the eigenfunctions and adjoint eigenfunctions. We show that the algebraic structure of the Virasoro symmetry is retained under discretization from the constrained multicomponent KP hierarchy to the discrete constrained multicomponent KP hierarchy.
Keywords:
constrained multicomponent KP hierarchy, discrete constrained multicomponent KP hierarchy, Virasoro symmetry.
