Monotonicity of Causal Killing Vectors and Geometry of ADM Mass Minimizers
Lan-Hsuan Huang (University of Connecticut)
Abstract
We present recent results on ADM mass–minimizing initial data sets: first, the equality case of the positive mass theorem, and second, Bartnik’s stationary vacuum conjecture arising from his quasi-local mass program.
A key new ingredient is a monotonicity formula for the Lorentzian length of a causal Killing vector field. This is joint work with Sven Hirsch.
