Title: "Phenomenology of multidimensional cosmological models"

The brane-world models, in which the space-time is decribed by a five (or more) -dimensional manifold with matter fields confied in a domain wall or three-brane, are reviewed. These models arise in the framework of M theory. Particular attention is paid to the generalized Randall-Sundrum models (covariant approach), the Cardassian scenario, the induced gravity models, the self-tuning models and the Ekpyrotic scenario. We discuss their basic properties and connection with the conventional cosmology.
