Big Bang Nucleosynthesis constraints on space-time noncommutativity
Teodora Maria Matei, Cristian Croitoru, Tiberiu Harko
We consider the implications of the modified dispersion relations, due to the noncommutativity of the spacetime, for a photon gas filling the early Universe in the framework of the…

Big Bang Nucleosynthesis constraints on the cosmological evolution in a Universe with a Weylian Boundary
Teodora M. Matei, Cristian Croitoru, Tiberiu Harko
We investigate the effects that arise from the inclusion of Weylian boundary terms in the Einstein gravitational field equations in the Big Bang Nucleosynthesis (BBN) framework. Wi…
