Sharp global regularity for the 2+1-dimensional equivariant Faddeev
model    [PDF]

Dan-Andrei Geba, Kenji Nakanishi, Xiang Zhang

The aim of this article is to prove that for the 2+1-dimensional equivariant Faddeev model, which is a quasilinear generalization of the corresponding nonlinear sigma model, small initial data in critical Besov spaces evolve into global solutions which scatter.
