Abstract(s)
In this paper, new exact solutions for locally rotational symmetric (LRS)
space-times are obtained within the modified Brans-Dicke theory (MBDT) (Rasouli
et al 2014 Class. Quantum Grav. 31 115002). Specifically, extended
five-dimensional (5D) versions of Kantowski-Sachs, LRS Bianchi type I and
Bianchi type III are investigated in the context of the standard Brans-Dicke
theory. We subsequently extract their corresponding dynamics on a 4D
hypersurface. Our results are discussed regarding others obtained in the
standard Brans-Dicke theory, induced-matter theory and general relativity.
Moreover, we comment on the evolution of the scale factor of the extra spatial
dimension, which is of interest in Kaluza-Klein frameworks.
