We have used the exact propagators corresponding to a finite number of points in the fifth dimensions, and results were obtained for several choices of the domain-wall parameters.Talk presented at Lattice 2007, the XXV International Symposium on Lattice Field Theory (Chiral symmetry), 7 pagesHigh Energy Physics - Latticetext
