Nonsingular FRW cosmology and nonlinear electrodynamics
C. S. Camara, M. R. de Garcia Maia, J. C. Carvalho +1
The possibility to avoid the cosmic initial singularity as a consequence of nonlinear effects on the Maxwell eletromagnetic theory is discussed. For a flat FRW geometry we derive t…

Quantum corrections to Maxwell electrodynamics in a homogeneous and isotropic universe with cosmological constant
M. R. de Garcia Maia, J. C. Carvalho, C. S. da Câmara Neto
Some cosmological consequences of first order quantum corrections to Maxwell electrodynamics are investigated in the context of a spatially flat homogeneous and isotropic universe…
