Asymptotics of Killing horizons: A Characterization in de Sitter Spacetime
Carlos Peón-Nieto
We prove that (n + 1)-dimensional de Sitter spacetime is locally the unique -vacuum spacetime whose Killing horizons intersect the conformal boundary . The int…

Classification of -vacuum algebraically special spacetimes with conformally flat from Weyl tensor expansion
Marc Mars, Carlos Peón-Nieto
We introduce a general algebraic decomposition of Riemann-like and Weyl-like tensors with respect to a non-null vector . We derive Gauss, Codazzi and Ricci-type identities for t…

Conformal Einstein equation and symplectic flux with a positive cosmological constant
Sk Jahanur Hoque, Pavel Krtouš, Carlos Peón-Nieto
We analyze the conformal Einstein equation with a positive cosmological constant to extract fall-off conditions of the gravitational fields. The fall-off conditions are consistent…
