Be careful with the Exp-function method
Nikolay A. Kudryashov, Nadejda B. Loguinova
An application of the Exp-function method to search for exact solutions of nonlinear differential equations is analyzed. Typical mistakes of application of the Exp-function method…
On Completely Integrability Systems of Differential Equations
Nikolay A. Kudryashov
In this note we discuss the approach which was given by Wazwaz for the proof of the complete integrability to the system of nonlinear differential equations. We show that his metho…

Nikolay A. Kudryashov, Dmitry I. Sinelshchikov
We discuss the recent paper by Inan and Ugurlu [Inan I.E., Ugurlu Y., Exp-function method for the exact solutions of fifth order KdV equation and modified Burgers equation, Appl. M…
Unnecessary Exact Solutions of Nonlinear Ordinary Differential Equations
Nikolay A. Kudryashov
We analyze the paper by Wazwaz and Mehanna [Wazwaz A.M., Mehanna M.S., A variety of exact travelling wave solutions for the (2+1) -- dimensional Boiti -- Leon -- Pempinelli equatio…
