On the horizon entropy of a causal set
Ludovico Machet, Jinzhao Wang
We discuss how to define a kinematical horizon entropy on a causal set. We extend a recent definition of horizon molecules to a setting with a null hypersurface crossing the horizo…
On the continuum limit of Benincasa-Dowker-Glaser causal set action
Ludovico Machet, Jinzhao Wang
We study the continuum limit of the Benincasa-Dowker-Glaser causal set action on a causally convex compact region. In particular, we compute the action of a causal set randomly spr…
The small sphere limit of quasilocal energy in higher dimensions along lightcone cuts
Jinzhao Wang
The problem of quasilocal energy has been extensively studied mainly in four dimensions. Here we report results regarding the quasilocal energy in spacetime dimension . Af…
Local gravitational energy in higher dimensions
Jinzhao Wang
In general relativity, the local gravitational energy is best characterised by the quasilocal mass. The small sphere limit of quasilocal mass provides us the most local notion of g…
Geometry of small causal diamonds
Jinzhao Wang
The geometry of small causal diamonds is systematically studied, based on three distinct constructions that are common in the literature, namely the geodesic ball, the Alexandrov i…
