In mathematics, the Calogero–Degasperis–Fokas equation is the nonlinear partial differential equation
u t = u x x x − 1 8 u x 3 + u x ( A e u + B e − u ) . {\displaystyle \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.
