Anisotropic Cosmology with Inhomogeneous $S U (2)$ and $S L (2, R)$ Nonlinear $σ$ -Models

N. Dimakis, A. Giacomini, G. Leon +2

We investigate the cosmological dynamics of the nonlinear $σ$ -model in a locally rotational symmetric Bianchi V background geometry. We employ the $S U (2)$ and the $SL(2,\mathbb{R})…

Bianchi I spacetimes within 4D Einstein-Gauss-Bonnet scalar field theory

Alex Giacomini, Chevara Hansraj, Genly Leon +1

We investigate the evolution of anisotropies in Bianchi I spacetimes within the framework of the 4D Einstein-Gauss-Bonnet scalar field theory. The field equations are formulated us…
