Abstract

We consider the bosonic and fermionic symmetries of five-dimensional Maxwell– and Yang–Mills–Einstein supergravity theories on a spacetime with boundaries (isomorphic to M×S1/ℤ2). Due to the appearance of the "Chern–Simons" term, the classical action is not generally invariant under gauge and supersymmetries. Once bulk vector fields are allowed to propagate on the boundaries, there is an "inflow" governed by the rank-3 symmetric tensor that defines the five-dimensional theories. We discuss the requirements that invariance of the action imposes on new matter content and boundary conditions.
