Minimal Surfaces with Stratified Branching Sets

Federico Franceschini, Rafe Mazzeo, Paul Minter

Inspired by the Taubes-Wu construction of two-valued harmonic functions by the use of symmetry, we construct minimal surfaces with stratified branching sets as…

ALG gravitational instantons and Hitchin moduli spaces, I: Torelli parameters

Laura Fredrickson, Rafe Mazzeo, Jan Swoboda +1

This is the first of two papers which together prove that the -parameter family of parabolic -Hitchin moduli spaces on the four-punctured sphere are all ALG gravitationa…

An index theorem for Z/2-harmonic spinors branching along a graph

Andriy Haydys, Rafe Mazzeo, Ryosuke Takahashi

We prove an index formula for the Dirac operator acting on two-valued spinors on a -manifold which branch along a smoothly embedded graph , and with respect to…

Solving the Scattering Problem for Open Wave-Guide Networks, III: Radiation Conditions and Uniqueness

Charles L. Epstein, Rafe Mazzeo

This paper continues the analysis of the scattering problem for a network of open wave-guides started in [arXiv:2302.04353, arXiv:2310.05816]. In this part we present explicit, phy…

Tian--Yau metrics: Fredholm theory, Hodge cohomology and moduli spaces

Rafe Mazzeo, Xuwen Zhu

We study the natural geometric elliptic operators on a class of complete Riemannian manifolds which include the 4-dimensional ALH* gravitational instantons and their higher dimensi…

Linear and nonlinear stability for the Bach flow, I

Eric Bahuaud, Christine Guenther, James Isenberg +1

In this paper we prove the linear stability of a gauge-modified version of the Bach flow on any complete manifold (M, h) of constant curvature. This involves some intricate calcula…
