摘要
We investigate the evolution of the gravitational potential in Rastall scalar field theories. In a single component model a consistent perturbation theory, formulated in the Newtonian gauge, is possible only for gamma = 1, which is the General Relativity limit. On the other hand, the addition of another canonical fluid component allows to consider the case gamma not equal 1. 0 2012 Elsevier B.V.
