Boundary fermions and the plane wave
  We construct branes in the plane wave background under the inclusion of fermionic boundary fields. The resulting deformed boundary conditions in the bosonic and fermionic sectors give rise to new integrable and supersymmetric branes of type (n,n). The extremal case of the spacetime filling (4,4)-brane is shown to be maximally spacetime supersymmetric.
