Lie symmetry analysis and conservation law for the equation arising from higher order Broer-Kaup equation

Autor: Wang Hengtai, Chen Huiwen, Ouyang Zigen, Li Fubin

Publikováno v: Open Mathematics, Vol 17, Iss 1, Pp 1045-1054 (2019)

In this paper, Lie symmetry analysis is performed for the equation derived from $(2+1)$-dimensional higher order Broer-Kaup equation. Meanwhile, the optimal system and similarity reductions based on the Lie group method are obtained. Furthermore, the

Existence of Positive Solutions to a Boundary Value Problem for a Delayed Nonlinear Fractional Differential System

Autor: Chen Yuming, Zou Shuliang, Ouyang Zigen

Publikováno v: Boundary Value Problems, Vol 2011, Iss 1, p 475126 (2011)

Though boundary value problems for fractional differential equations have been extensively studied, most of the studies focus on scalar equations and the fractional order between 1 and 2. On the other hand, delay is natural in practical systems. Howe

Existence and multiplicity of sign-changing standing waves for a gauged nonlinear Schr\'{o}dinger equation in $\R^2$

Autor: Liu, Zhisu, Ouyang, Zigen, Zhang, Jianjun

We are concerned with sign-changing solutions of the following gauged nonlinear Schr\"{o}dinger equation in dimension two including the so-called Chern-Simons term \begin{align*} \left\{ \begin{array}{ll} -\triangle {u}+\omega u+\left(\frac{h^2(|x|)}
