Abstract

In this paper, we investigate the Cauchy problem for the stochastic Kawahara equation,
which is a fifth-order shallow water wave equation. We prove local well-posedness for
data in Hs (R), s > −7/4. Moreover, we get global existence for L2(R) solutions. Due to
the non-zero singularity of the phase function, a fixed point argument and Fourier
restriction method are proposed.
