Lifting General Relativity to Observer Space
Steffen Gielen, Derek K. Wise
The `observer space' of a Lorentzian spacetime is the space of future-timelike unit tangent vectors. Using Cartan geometry, we first study the structure a given spacetime induces o…

Linking Covariant and Canonical General Relativity via Local Observers
Steffen Gielen, Derek K. Wise
Hamiltonian gravity, relying on arbitrary choices of "space," can obscure spacetime symmetries. We present an alternative, manifestly spacetime covariant formulation that nonethele…

Teleparallel Gravity as a Higher Gauge Theory
John C. Baez, Derek K. Wise
We show that general relativity can be viewed as a higher gauge theory involving a categorical group, or 2-group, called the teleparallel 2-group. On any semi-Riemannian manifold M…
