Existence and evenness of solitary-wave solutions for an equation of short and long dispersive waves

, 2015
We study the existence and some properties of solitary-wave solutions for an interaction equation between a long internal wave and a short surface wave in a two-layer fluid.

Local well-posedness for the two-component Benjamin-Ono equation

Advances in Nonlinear Analysis
The Cauchy problem for the two-component Benjamin-Ono equation is considered. It is shown that this problem is local well-posed in Hs(R)×Hs(R){H}^{s}\left({\mathbb{R}})\times {H}^{s}\left({\mathbb{R}}) for any s>9⁄8s\gt 9/8.
