Boundary Terms for Globally Supersymmetric Actions
Research Report 94-41
Date: 7 December 1994
Supersymmetry is always broken on a manifold-with-boundary, since the
supersymmetric variation of the Lagrangian is a total divergence which yields a
boundary term when integrated. If attention is restricted to a subalgebra of
generators which preserve the boundary, the invariance of the action can be
restored by adding a boundary correction whose variation cancels that from the
integrated Lagrangian. One can also impose boundary conditions which are
invariant under this subalgebra.
