Area-metric gravity revisited (2024)
Journal Article

Area metrics are an intriguing generalization of length metrics which the generalization in several quantum-gravity approaches. We describe the space of diffeomorphism-invariant area-metric actions quadratic in fluctuations and derivatives. A general... Read More about Area-metric gravity revisited.

Lorentzian Cayley form (2024)
Journal Article

Cayley four-form Φ on an eight-dimensional manifold M is a real differential form of a special algebraic type, which determines a Riemannian metric on M as well as a unit real Weyl spinor. It defines a Spin(7) structure on M, and this Spin(7) structu... Read More about Lorentzian Cayley form.
