A First-Order Gauge Approach to de Sitter General Relativity
P. Salgado
We propose a first-order gauge formulation of de Sitter relativity in which the pseudo-radius l(x) is promoted to a spacetime field, locally breaking SO(4,1) to SO(3,1). Here, l(x)…

Geometric origin of the cosmological constant from Einstein-Chern-Simons gravity compactified to four dimensions
M. Cataldo, S. Lepe, C. Riquelme +1
We present a model in which the cosmological constant emerges as a purely geometric effect from the four-dimensional compactification of five-dimensional Einstein-Chern-Simons grav…
