Symmetry reduction of gravitational Lagrangians
Guillermo Frausto, Ivan Kolář, Tomáš Málek +1
We analyze all possible symmetry reductions of Lagrangians that yield fully equivalent field equations for any 4-dimensional metric theory of gravity. Specifically, we present a co…
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…
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…
Exact solutions of non-local gravity in a class of almost universal spacetimes
Ivan Kolář, Tomáš Málek, Anupam Mazumdar
We study exact solutions of the infinite derivative gravity with null radiation which belong to the class of almost universal Weyl type III/N Kundt spacetimes. This class is define…
