Nonsingular FRW cosmology and nonlinear electrodynamics

Abstract: 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 the general nonsingular solution supported by a magnetic field plus a cosmic fluid and a nonvanishing vacuum energy density.The nonsingular behavior of solutions with a time-dependent Λ(t)-term are also examined. As a general result, it is found that the functional dependence of Λ(t) can uniquely be determined only if the magnetic fie… Show more

“…We should note that the removal of initial singularities is due to Non-Linear Electrodynamics, as seen in [7], by Camara et al, which is also in tandem with [18] [19] [20] which give also frequency specifications, which could also affect mn ω , i.e. a tie in, with Gravitons, and Nonlinear Electrodynamics, which should be developed further.…”
