摘要：

In this paper, we consider the local well-posedness of the wave equation with null form nonlinearities under the periodic boundary condition. First, we prove the local existence based on some L-p-based Sobolev like Space (H) over cap (s,p), where s > 1/2 + d/p' for d >= 2, s >= 1/2, for d = 1. Second, we prove the local existence for randomized initial data in H-s with s > 1/2 and d >= 2.
