# Calogero–Degasperis–Fokas equation

In mathematics, the Calogero–Degasperis–Fokas equation is the nonlinear partial differential equation

    $\displaystyle u_{t}=u_{xxx}-{\frac {1}{8}}u_{x}^{3}+u_{x}\left(Ae^{u}+Be^{-u}\right).$

This equation was named after F. Calogero, A. Degasperis, and A. Fokas.
