A nonlocal variable coefficient modified KdV equation derived from two-layer fluid system and its exact solutions
Xi-Zhong Liu
A nonlocal form of a two-layer fluid system is proposed by a simple symmetry reduction, then by applying multiple scale method to it a general nonlocal two place variable coefficie…

A nonlocal nonlinear Schrodinger equation derived from a two-layer fluid model
Xi-Zhong Liu
By applying a simple symmetry reduction on a two-layer liquid model, a nonlocal counterpart of it is obtained. Then a general form of nonlocal nonlinear Schrodinger (NNLS) equatio…

Symmetry group theorem to the Lin-Tsien equation and conservation laws relating to the symmetry of the equation?
Liu Xi-Zhong
In this paper, We derive the symmetry group theorem to the Lin-Tsien equation by using the modified CK's direct method, from which we obtain the corresponding symmetry group. More…
