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…

High dimensional Schwarzian derivatives and Painlevé integrable models
Sen-yue Lou, Shun-li Zhang, Xiao-yan Tang
Because of all the known integrable models possess Schwarzian forms with Möbious transformation invariance, it may be one of the best way to find new integrable models starting fro…

Chaos in soliton systems and special Lax pairs for chaos systems
Sen-yue Lou, Xiao-yan Tang, Ying Zhang
In this letter, taking the well known (2+1)-dimensional soliton systems, Davey-Stewartson (DS) model and the asymmetric Nizhnik-Novikov-Veselov (ANNV) model, as two special example…
