A Five-dimensional Kaluza-Klein Approach to Unimodular Gravity
Júlio C. Fabris, Richard Kerner
In this article we present a possibility of imposing the unimodular condition within the 5-dimensional Kaluza-Klein theory including the scalar field. Unimodular gravity became an…

On the Stability of Non-Singular Solutions in Effective Theory from Kaluza-Klein Unimodular Gravity
Júlio C. Fabris, Richard Kerner
Unimodular theory incorporating the Kaluza-Klein construction in five dimensions leads, after reduction to four dimensions, to a new class of scalar-tensor theory. The vacuum cosmo…
