We show that the structure of the Lorentz group in four dimensions is such that unimodular (trace-free) gravity can be consistently represented as an algebraic condition on the sym…

Topological Origin of Horizon Temperature via the Chern-Gauss-Bonnet Theorem
Jack C. M. Hughes, Fedor V. Kusmartsev
This paper establishes a connection between the Hawking temperature of spacetime horizons and global topological invariants, specifically the Euler characteristic of Wick-rotated E…
