Low energy $\varepsilon$-harmonic maps into the round sphere

Abstract

In this paper we classify the low energy ε\varepsilon-harmonic maps from the surfaces of constant curvature with positive genus into the round sphere. We find that all such maps with degree ±1\pm1 are all quantitively close to a bubble configuration with bubbles forming at special points on the domain with bubbling radius proportional to ε1/4\varepsilon^{1/4}.
