Consider the general dispersive equation defined by where φ() is a pseudo-differential operator with symbol φ(|ξ|). In this paper, for φ satisfying suitable growth conditions and the radial initial data f in Sobolev space, we give the local and global Lq estimate for the maximal operator defined by f(x) = sup0<t<1|St,φf(x)|, where St,φfis the solution of equation (∗). These estimates imply the a.e. convergence of the solution of equation (∗).
