A Riemann-Hilbert approach to existence of global solutions to the Fokas-Lenells equation on the line

Qiaoyuan Cheng, Engui Fan

We obtain the the existence of global solutions to the Cauchy problem of the Fokas-Lenells (FL) equation on the line \begin{align} &u_{xt}+αβ^2u-2iαβu_x-αu_{xx}-iαβ^2|u|^2u_x=0,\no…

Long-time asymptotics for the focusing Fokas-Lenells equation in the solitonic region of space-time

Qiaoyuan Cheng, Engui Fan

We study the long-time asymptotic behavior of the focusing Fokas-Lenells (FL) equation $$ u_{xt}+αβ^2u-2iαβu_x-αu_{xx}-iαβ^2|u|^2u_x=0 \label{cs} $$ with generic initial data in a…
