The integrable hierarchy and the nonlinear Riemann-Hilbert problem associated with one typical Einstein-Weyl physico-geometric dispersionless system
Ge Yi, Tangna Lv, Kelei Tian +1
From a specific series of exchange conditions for a one-parameter Hamiltonian vector field, we establish an integrable hierarchy using Lax pairs derived from the dispersionless par…

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…
