On a matrix constrained CKP hierarchy
Song Li, Kelei Tian, Zhiwei Wu
The algebraic structures of integrable hierarchies play an important role in the study of soliton equations. In this paper, we use splitting theory to give a matrix representation…

On the c-k constrained KP and BKP hierarchies: the Fermionic pictures, solutions and additional symmetries
Kelei Tian, Song Li, Ge Yi +2
In this paper, we study two generalized constrained integrable hierarchies, which are called the - constrained KP and BKP hierarchies. The Fermionic picture of the - co…
