The Classification of Branched Willmore Spheres in the 3-Sphere and the 4-Sphere

open access: yesAnnales scientifiques de l'École Normale Supérieure, 2022
We extend the classification of Robert Bryant of Willmore spheres in $S^3$ to variational branched Willmore spheres $S^3$ and show that they are inverse stereographic projections of complete minimal surfaces with finite total curvature in $\mathbb{R}^3$ and vanishing flux. We also obtain a classification of variational branched Willmore spheres in $S^4$
