The brane worlds obtained correspond to Eötvös branes whose (internal) geometry can be casted as either a four-dimensional (A)dS4 or a standard radiation period cosmology. The matter dominated period is discussed as well. © 2017 Chinese Physical Society and IOP Publishing Ltd.enbrane tensionbrane worldde Sitterhierarchy problemRandall-SundrumArtículoCC BY 3.0 CL DEED10.1088/0253-6102/68/5/595
