Quasi-topological gravity for 4-dimensional Taub-NUT, near-horizon extreme Kerr, and swirling symmetries
Aimeric Colléaux, Ivan Kolář, Tomáš Málek
We classify 4-dimensional gravitational theories with integrability properties analogous to quasi-topological gravity, but for metrics with the symmetries of spherical, hyperbolic,…
Static spherically symmetric Kundt vacuum solutions of higher-derivative gravities
Breno L. Giacchini, Ivan Kolář, Vojtěch Pravda +1
We study static spherically symmetric Kundt solutions to the vacuum field equations of quadratic gravity with a cosmological constant, as well as specific models of six-derivative…
Canonical quantization of all minisuperspaces with consistent symmetry reductions
Poula Tadros, Ivan Kolář, Otakar Svítek
We present the quantization of all symmetry reductions of the Einstein--Hilbert Lagrangian that correctly reproduce the reduced Einstein's field equations -- i.e., characterized by…
