Resumen:
In this talk we present new solutions of the EGB field equations in a SMS brane-world setting which represent acouple of Z2-symmetric vacuum thin shells splitting from the central brane, and explore the main properties ofthe dynamics of the system. The matching of the separating vacuum shells with the brane-world is as smooth aspossible and all matter fields are restricted to the brane. Several implications for the effective Friedmann equationson the brane are discussed, and compared with standard cosmology. We also comment on the relation of thissystem with the thermodynamic instability of highly symmetric vacuum solutions of Lovelock theory
