The Newman-Penrose map and the classical double copy
Gauge-gravity duality is arguably our best hope for understanding quantum gravity. Considerable progress has been made in relating scattering amplitudes in certain gravity theories to those in gauge theories

Clausius equation for horizons in F(R)-gravity
Covariant Hamiltonian formulation of F(R) gravity is used to find variation of surface Hamiltonian which leads to formulation of temperature and entropy of a horizon. These thermodynamic quantities are then used to establish an analogy betwe...

On the Quantum Regularization of Singular Black-Hole Solutions in Covariant Quantum Gravity
regularization of singular black-hole solutions of classical general relativity. The problem is posed in the context of the theory of covariant quantum gravity (CQG-theory), namely the theory in a frame-i...

Remarks on doubly special relativity theories and gravity
Modifications of special relativity by the introduction of an invariant energy and/or momentum level (doubly special relativity, DSR) or by an energy-momentum dependence of the Planck constant (generalized uncertainty principle, GUP) are compared wit...

Spectral action approach to higher derivative gravity
We study the spectral action approach to higher derivative gravity. The work focuses on the classical aspects. We derive the complete and simplified form a rather rigid structure of the higher derivative part of the theory....
