In particular we obtain phantom scenarios for two cosmological frameworks. In the first framework we deal with an induced 4D de-Sitter expansion and in the second one a 4D induced model where the expansion of the universe is dominated by a decreasing cosmological parameter $Λ(t)$ is discussed.version accepted in Physics Letters BGeneral Relativity and Quantum CosmologyPassing to an effective 4D phantom cosmology from 5D vacuum theory of gravitytext
