Publication date: Available online 9 January 2020Source: Physics Letters AAuthor(s): Gangwei Wang, Jose Vega–Guzman, Anjan Biswas, Abdullah Kamis Alzahrani, A.H. KaraAbstractWe analyze domain wall type solutions, symmetry/invariance properties and conservation laws of the (2+1)-dimensional Boiti–Leon–Pempinelli system which describes the evolution of the horizontal velocity component of water waves propagating in two directions. It turns out that the equation is extensive in these properties. Some domain wall properties are also investigated.
