The Benjamin-Ono equation is a nonlinear partial integro-differential equation. It was introduced by Benjamin (1967) and Ono (1975) as an equation describing one-dimensional internal waves in deep water.
The Benjamin-Ono equation has a form
where is the Hilbert transform.
It is a soliton equation and can be solved by an inverse scattering transform.
