On constraining the speed of gravitational waves following GW150914
Diego Blas, Mikhail M. Ivanov, Ignacy Sawicki +1
We point out that the observed time delay between the detection of the signal at the Hanford and Livingston LIGO sites from the gravitational wave event GW150914 places an upper bo…
Asymptotic solutions in f(R)-gravity
Evgeny E. Bukzhalev, Mikhail M. Ivanov, Alexey V. Toporensky
We study cosmological solutions in -gravity for an isotropic Universe filled with ordinary matter with the equation of state parameter . Using the Bogolyubov-Krylov-…
Stable super-inflating cosmological solutions in f(R)-gravity
Mikhail M. Ivanov, Alexey V. Toporensky
We consider super-inflating solutions in modified gravity for several popular families of functions. Using scalar field reformulation of -gravity we describe how the f…
Cosmological dynamics of fourth order gravity with a Gauss-Bonnet term
Mikhail M. Ivanov, Alexey V. Toporensky
We consider cosmological dynamics in fourth order gravity with both and correction to the Einstein gravity ( is the Gauss-Bonnet term). The pa…
Entropy Bounds, Holographic Principle and Uncertainty Relation
M. G. Ivanov, I. V. Volovich
A simple derivation of the bound on entropy is given and the holographic principle is discussed. We estimate the number of quantum states inside space region on the base of uncerta…
