Second order Lax pairs of nonlinear partial differential equations with Schwarz variants
Sen-yue Lou, Xiao-yan Tang, Qing-Ping Liu +1
In this paper, we study the possible second order Lax operators for all the possible (1+1)-dimensional models with Schwarz variants and some special types of high dimensional model…

Miura Map between Lattice KP and its Modification is Canonical
Q. P. Liu
We consider the Miura map between the lattice KP hierarchy and the lattice modified KP hierarchy and prove that the map is canonical not only between the first Hamiltonian structur…
