Gravitational waves from a Weyl-Integrable manifold: a new formalism
Jesús Martín Romero, Mauricio Bellini, José Edgar Madriz Aguilar
We study the variational principle over an Hilbert-Einstein like action for an extended geometry taking into account torsion and non-metricity. By extending the semi-Riemannian geo…

Gauge invariant fluctuations of the metric during inflation from new scalar-tensor Weyl-Integrable gravity model
M. L. Pucheu, C. Romero, M. Bellini +1
We investigate gauge invariant scalar fluctuations of the metric during inflation in a non-perturbative formalism in the framework of a recently introduced scalar-tensor theory of…

New effective coupled modified gravity from gravity in five dimensions
Jose Edgar Madriz Aguilar
We obtain a new kind of modified gravity theory as an effective four-dimensional (4D) theory derived from gravity in five dimensions (5D). This new…
