Abstract

We consider wave maps from (1+d)(1+d)-dimensional Minkowski space, d3d\geq3, into rotationally symmetric manifolds which arise from small perturbations of the sphere Sd\mathbb S^d. We prove the existence of co-rotational self-similar finite time blowup solutions with smooth blowup profiles. Furthermore, we show the nonlinear asymptotic stability of these solutions under suitably small co-rotational perturbations on the full space.
