Brane cosmology with variable tension
José Antonio Belinchón, Sami Dib
We study brane-world models and demonstrate that such models do not admit self-similar solutions through the matter collineation approach. By introducing the hypothesis of variable…
Normalized angular momentum deficit: A tool for comparing the violence of the dynamical histories of planetary systems
D. Turrini, A. Zinzi, J. A. Belinchon
Population studies of the orbital characteristics of exoplanets in multi-planet systems have highlighted the existence of an anticorrelation between the average orbital eccentricit…
Approximate Analytical Solution for the Dynamic Model of Large Amplitude Non-Linear Oscillations Arising in Structural Engineering
J. A. Belinchon, T. Harko, M. K. Mak
In this work we obtain an approximate solution of the strongly nonlinear second order differential equation $\frac{d^{2}u}{dt^{2}}+ω^{2}u+αu^{2}\frac{d^{2}u}{dt^{2}}+αu\left( \frac…
Extension of a factorization method of nonlinear second order ODE's with variable coefficients
H. C. Rosu, O. Cornejo-Perez, M. Perez-Maldonado +1
The factorization of nonlinear second-order differential equations proposed by Rosu and Cornejo-Perez in 2005 is extended to equations containing quadratic and cubic forms in the f…
Exact Scalar-Tensor Cosmological Solutions via Noether Symmetry
J. A. Belinchón, T. Harko, M. K. Mak
In this paper, we investigate the Noether symmetries of a generalized scalar-tensor, Brans-Dicke type cosmological model, in which we consider explicit scalar field dependent coupl…
(An)Isotropic models in scalar and scalar-tensor cosmologies
José Antonio Belinchón
We study how the constants and may vary in different theoretical models (general relativity with a perfect fluid, scalar cosmological models (\textquotedblleft quintessence…
