Exact solitary waves of a nonlinear network equation

摘要

We show by using the real exponential approach that the well-known discrete modified Korteweg-de Vries equation and nonlinear network equations have more general exact soliton solutions than the known bright soliton and kink solutions. Depending on the values of the parameters, the new solutions can describe a series of bright solitons, dark solitons, and kink solitons. [References: 10]
