      abstract     = {We investigate the Brillouin action in terms of its
                      suitability as a kernel to the overlap procedure, with a
                      view on both heavy and light quark physics. We use the
                      diagonal elements of the Kenney-Laub family of iterations
                      for the sparse matrix sign function, since they grow
                      monotonically and facilitate cascaded preconditioning
                      strategies with different rational approximations to the
                      sign function. We find that the overlap action with the
                      Brillouin kernel is significantly better localized than the
                      version with the Wilson kernel.},
