Exact Scalar-Tensor Cosmological Models
J. A. Belinchón, T. Harko, M. K. Mak
Scalar-tensor gravitational theories are important extensions of standard general relativity, which can explain both the initial inflationary evolution, as well as the late acceler…
Exact travelling wave solutions of non-linear reaction-convection-diffusion equations -- an Abel equation based approach
T. Harko, M. K. Mak
We consider quasi-stationary (travelling wave type) solutions to a general nonlinear reaction-convection-diffusion equation with arbitrary, autonomous coefficients. The second orde…
Full Causal Bulk Viscous Cosmological Models with Variable G and Lambda
J. A. Belinchon, T. Harko, M. K. Mak
We study the evolution of a flat Friedmann-Robertson- Walker Universe, filled with a bulk viscous cosmological fluid, in the presence of variable gravitational and cosmological con…
Exact anisotropic brane cosmologies
Chiang-Mei Chen, T. Harko, M. K. Mak
We present exact solutions of the gravitational field equations in the generalized Randall-Sundrum model for an anisotropic brane with Bianchi type I and V geometry, with perfect f…
Anisotropic Four-Dimensional NS-NS String Cosmology
Chiang-Mei Chen, T. Harko, M. K. Mak
An anisotropic (Bianchi type I) cosmology is considered in the four-dimensional NS-NS sector of low-energy effective string theory coupled to a dilaton and an axion-like -field…
