Abstract
A large N expansion for gravity is proposed. The scheme is based on the splitting of the Einstein-Hilbert action into the BF topological action plus a constraint. The method also allows to include matter fields. The relation between matter and nonorientable fat graphs in the expansion is stressed; the special role of scalars is shortly discussed. The connections with the holographic principle and higher spin fields are analyzed.
