We consider 1-equivariant wave maps from Rt×(Rx3∖B)→S3where B is a ball centered at 0, and ∂B gets mapped to a fixed point on S3. We show that 1-equivariant maps of degree zero scatter to zero irrespective of their energy. For positive degrees, we prove asymptotic stability of the unique harmonic maps in the energy class determined by the degree.
