The DWF formulation becomes increasingly problematic at gauge couplings for
which a−1<2 GeV, where the roughness of the gauge field leads to increased
explicit chiral symmetry breaking (\mres). This problem becomes especially
severe for sufficiently strong coupling where the underlying 4-dimensional
Wilson theory is in the Aoki phase. We review our attempts to find a suitable
modification of the gauge and/or the fermion action which would allow the DWF
method to work reliably at stronger coupling.Comment: 4 pages, 4 figures, Lattice2004(chiral
