Elliptic solutions of generalized Brans-Dicke gravity with a non-universal coupling
J. -M. Alimi, A. A. Golubtsova, V. Reverdy
We study a model of the generalized Brans-Dicke gravity presented in both the Jordan and in the Einstein frames, which are conformally related. We show that the scalar field equati…
An S-brane solution with acceleration and small enough variation of G
J. -M. Alimi, V. D. Ivashchuk, V. N. Melnikov
An S-brane solution with two non-composite electric branes and a set of l scalar fields is considered. The intersection rule for branes corresponds to the Lie algebra A_2. The solu…
An Awesome Hypothesis for Dark Energy : The Abnormally Weighting Energy
A. Fuzfa, J. -M. Alimi
We introduce the Abnormally Weighting Energy (AWE) hypothesis in which dark energy (DE) is presented as a consequence of the violation of the weak equivalence principle (WEP) at co…
Multidimensional cosmology with anisotropic fluid: acceleration and variation of G
J. -M. Alimi, V. D. Ivashchuk, S. A. Kononogov +1
A multidimensional cosmological model describing the dynamics of n+1 Ricci-flat factor-spaces M_i in the presence of a one-component anisotropic fluid is considered. The pressures…
Correspondence between kinematical backreaction and scalar field cosmologies - the `morphon field'
Thomas Buchert, Julien Larena, Jean-Michel Alimi
Spatially averaged inhomogeneous cosmologies in classical general relativity can be written in the form of effective Friedmann equations with sources that include backreaction term…
Non-Abelian Einstein-Born-Infeld-Dilaton Cosmology
A. Fuzfa, J. -M. Alimi
The non-abelian Einstein-Born-Infeld-Dilaton theory, which rules the dynamics of tensor-scalar gravitation coupled to a -valued gauge field ruled by Born-Infeld lagrangian,…
