摘要：
this paper we prove that the initial value problem of the OST equation u(t) + u(xxx) + eta(Hu(x) + Hu(xxx)) + uu(x) = 0 (x is an element of R, t >= 0), where eta > 0 and H denotes the usual Hilbert transformation, is locally well-posed in the Sobolev space H-s(R) when s > -3/4, and globally well-posed in H-s(R) when s >= 0.
