Solutions with pure radiation and gyratons in 3D massive gravity theories
Ercan Kilicarslan, Ivan Kolář
We find exact solutions of topologically massive gravity (TMG) and new massive gravity (NMG) in dimensions (3D) with an arbitrary cosmological constant, pure radiation, and…
Infinite derivative gravity resolves nonscalar curvature singularities
Ivan Kolář, Tomáš Málek
We explicitly demonstrate that the nonlocal ghost-free ultraviolet modification of general relativity (GR) known as the infinite derivative gravity (IDG) resolves nonscalar curvatu…
Carrollian limit of quadratic gravity
Poula Tadros, Ivan Kolář
We study the Carrollian limit of the (general) quadratic gravity in four dimensions. We find that in order for the Carrollian theory to be a modification of the Carrollian limit of…
Propagators in AdS for higher-derivative and nonlocal gravity: Heat kernel approach
Ivan Kolář, Tomáš Málek
We present a new covariant method of construction of the (position space) propagators in the -dimensional (Euclidean) anti-de Sitter background for any gravitational theory with…
