摘　　要：In this work we study a brane world model with variable tension, which gives rise to four-dimensional cosmologies. The brane worlds obtained correspond to E?tv?s branes whose(internal) geometry can be casted as either a four-dimensional(A)dS_4 or a standard radiation period cosmology. The matter dominated period is discussed as well.In this work we study a brane world model with variable tension, which gives rise to four-dimensional cosmologies. The brahe worlds obtained correspond to Eftvfs 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.
