Abstract

We consider the time local well-posedness of the Benjamin equation. Like the result due to Kenig-Ponce-Vega [10], [12], we show that the initial value problem is time locally well posed in the Sobolev space $H^s(\mathbb R)$ for $s > - 3/4$.

Keywords: Benjamin equation, local well-posedness, initial value problem, KdV equation
