The Fokas-Lenells equation is considered taking into account the traveling wave reduction. It is shown that the exact solutions of this equation proposed in recent papers by N. Mahak and G. Akram are incorrect. The fallacy of the method for constructing exact solutions to the overdetermined system of equations by these authors is discussed. A correct method for constructing exact solutions of the Fokas-Lenells equation is presented and general solutions of this equation is given.

Mahak和Akram对Fokas-Lenells方程的结果的重新考察

考虑了行波衰减，考虑了Fokas-Lenells方程。结果表明，N。Mahak和G. Akram在最近的论文中提出的该方程的精确解是不正确的。这些作者讨论了为超定方程组构造精确解的方法的谬误。提出了构造Fokas-Lenells方程精确解的正确方法，并给出了该方程的一般解。
