Noether Symmetry Approach in $f (T, B)$ teleparallel cosmology

Sebastian Bahamonde, Salvatore Capozziello

We consider the cosmology derived from $f (T, B)$ gravity where $T$ is the torsion scalar and $B = \frac{2}{e} \partial_{μ} (e T^{μ})$ a boundary term. In particular we discuss how it is pos…

Cosmological expansion and contraction from Pauli exclusion principle in $M 0$ -branes

Alireza Sepehri, Ahmed Farag Ali, Kazuharu Bamba +5

We show that the Pauli exclusion principle in a system of $M 0$ -branes can give rise to the expansion and contraction of the universe which is located on an $M 3$ -brane. We start wit…
