Fine properties of branch point singularities: Dirichlet energy minimizing multi-valued functions

Brian Krummel, Neshan Wickramasekera

In the early 1980's Almgren developed a theory of Dirichlet energy minimizing multi-valued functions, proving that the Hausdorff dimension of the singular set (including branch poi…

On the regularity of the free boundary in the $p$ -Laplacian obstacle problem

Alessio Figalli, Brian Krummel, Xavier Ros-Oton

We study the regularity of the free boundary in the obstacle for the $p$ -Laplacian, $min {- Δ_{p} u, u - φ} = 0$ in $Ω \subset R^{n}$ . Here, $Δ_p u=\textrm{div}\bigl(|\na…
