# Willmore surfaces in $\R^3$

#### 09.11. bis 09.11.2021, 12:15-13:45  –  Room 2.09.2.22 Campus Golm, C9A03 Tübingen Geometric Analysis, Differential Geometry and Relativity

Nicolas Marque

When one considers a surface in $\R^3$, the mean curvature quickly appears as a node of geometric insight, tying itself to isoperimetry, elasticity, and regularity.  From it one can naturally build a quadratic energy linked with the elastic properties of the surface: the Willmore energy.
We will see how insights on Willmore informs our knowledge of the surface, and how its pecular behavior generates rich and surprising  phenomena for its critical points: noncompact bubbling. If time allows, we will also look at situations  where the aforementioned knowledges can be applied, notably to GR, or the sphere eversion.
