inflation to probe non-perturbative quantum gravity
Alexey S. Koshelev, K. Sravan Kumar, Alexei A. Starobinsky
It is natural to expect a consistent inflationary model of the very early Universe to be an effective theory of quantum gravity, at least at energies much less than the Planck one.…
Finite quantum gravity in dS and AdS spacetimes
Alexey S. Koshelev, K. Sravan Kumar, Leonardo Modesto +1
We hereby study the properties of a large class of weakly nonlocal gravitational theories around the (anti-) de Sitter spacetime background. In particular, we explicitly prove that…
Do massive compact objects without event horizon exist in infinite derivative gravity?
Alexey S. Koshelev, Anupam Mazumdar
Einstein's General theory of relativity is plagued by cosmological and blackhole type singularities Recently, it has been shown that infinite derivative, ghost free, gravity can yi…
On Nonlocal Modified Gravity and its Cosmological Solutions
Ivan Dimitrijevic, Branko Dragovich, Jelena Stankovic +2
During hundred years of General Relativity (GR), many significant gravitational phenomena have been predicted and discovered. General Relativity is still the best theory of gravity…
