Index estimates for constant mean curvature surfaces in three-manifolds by energy comparison
Luca Seemungal, Ben Sharp
We prove a linear upper bound on the Morse index of closed constant mean curvature (CMC) surfaces in orientable three-manifolds in terms of genus, number of branch points and a Wil…

A Note on Moving Frames along Sobolev Maps and the Regularity of Weakly Harmonic Maps
Luigi Appolloni, Ben Sharp
The purpose of this note is twofold. First we show that, for weakly differentiable maps between Riemannian manifolds of any dimension, a smallness condition on a Morrey-norm of the…
