Impulsive waves in ghost free infinite derivative gravity in anti-de Sitter spacetime
Suat Dengiz, Ercan Kilicarslan, Ivan Kolář +1
We study exact impulsive gravitational waves propagating in anti-de Sitter spacetime in the context of the ghost free infinite derivative gravity. We show that the source-free theo…
NUT charge in linearized infinite derivative gravity
Ivan Kolar, Anupam Mazumdar
We study the gravitational field of the NUT-like source in the linearized (ghost-free) infinite derivative gravity. Such a source is equivalent to the spinning semi-infinite cosmic…
Hamiltonian for scalar field model of infinite derivative gravity
Ivan Kolar, Anupam Mazumdar
Theories with an infinite number of derivatives are described by non-local Lagrangians for which the standard Hamiltonian formalism cannot be applied. Hamiltonians of special types…
Symmetry axes of Kerr-NUT-(A)dS spacetimes
Ivan Kolar, Pavel Krtous
We study fixed points of isometries of the higher-dimensional Kerr-NUT-(A)dS spacetimes that form generalizations of symmetry axes. It turns out that, in the presence of nonzero NU…
Weak electromagnetic field admitting integrability in Kerr-NUT-(A)dS spacetimes
Ivan Kolar, Pavel Krtous
We investigate properties of higher-dimensional generally rotating black-hole spacetimes, so called Kerr-NUT-(A)dS spacetimes, as well as a family of related spaces which share the…
