Observations on the tanh-coth expansion method for finding solutions to nonlinear evolution equations [PDF]

open access: yes, 2010
The 'tanh-coth expansion method' for finding solitary travelling-wave solutions to nonlinear evolution equations has been used extensively in the literature. It is a natural extension to the basic tanh-function expansion method which was developed in the
