Abstract: We discuss results regarding global existence of solutions for the critical generalized Korteweg-de Vries equation,

\begin{displaymath}u_t+u_{xxx}+u^4\,u_x=0,\quad x,\,t\in\mathbb{R} .\end{displaymath}

The theory established shows the existence of global solutions in Sobolev spaces with order below the one given by the energy space $H^1(\mathbb{R} )$, i.e. solutions corresponding to data $u_0\in H^s(\mathbb{R} )$, $s>3/4$, with $\Vert u_0\Vert _{L^2}<\Vert Q\Vert _{L^2}$, where $Q$ is the solitary wave solution of the equation.
