摘要

We show that the nonlinear wave equation □u + u_t~3 = 0 is globally well-posed in radially symmetric Sobolev spaces H_(rad)~k(R~3) × H_(rad)~(k-1)(R~3} for all integers k > 2. This partially extends the well-posedness in H~k(R~3) × H~(k-1)(R~3) for all k ∈ [1, 2], established by Lions and Strauss [12]. As a consequence we obtain the global existence of C~∞ solutions with radial C_0~∞ data. The regularity problem requires smoothing and non-concentration estimates in addition to standard energy estimates, since the cubic damping is critical when k = 2. We also establish scattering results for initial data (u,u_t)|_(t=0) in radially symmetric Sobolev spaces.
