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

Well-posedness of a higher-order Schrödinger–Poisson–Slater system

open access: yesBoundary Value Problems, 2018
In this paper, we show the global well-posedness of a higher-order nonlinear Schrödinger equation. Specifically, we consider a system of infinitely many coupled higher-order Schrödinger–Poisson–Slater equations with a self-consistent Coulomb potential ...
