Description

Multigrid (MG) methods for the computation of propagators of staggered fermions in non-Abelian gauge fields are discussed. MG could work in principle in arbitrarily disordered systems. The practical variational MG methods tested so far with a 'Laplacian choice' for the restriction operator are not competitive with the conjugate gradient algorithm on lattices up to 184. Numerical results are presented for propagators in SU(2) gauge fields. (orig.)
