Résumé
The Willmore energy arises naturally as a measure of how curved an immersed surface in $mathbb{R}^3$ is, with applications in relativity (the Hawking mass). Willmore immersions are critical points of this energy. We will study sequences of Willmore surfaces, which are subject to concentration-compactness i.e. : bubbling phenomena. We will focus on simple minimal bubbles, and detail consequences on the compactness below certain thresholds.
