Query: Discrete Fourier restriction associated with KdV equations   In this paper, we consider a discrete restriction associated with KdV
equations. Some new Strichartz estimates are obtained. We also establish the
local well-posedness for the periodic generalized Korteweg-de Vries equation
with nonlinear term $ F(u)\p_x u$ provided $F\in C^5$ and the initial data
$\phi\in H^s$ with $s>1/2$.
