Low-energy $${\alpha }$$-harmonic maps into the round sphere

Abstract We classify low-energy $$\alpha $$ α -harmonic maps from a closed non-spherical Riemannian surface $$\Sigma $$ Σ of constant curvature to the round sphere via their bubble scales and centres. In particular we show that as $$1<\alpha \downarrow 1$$ 1 < α ↓ 1 and assuming...
