Abstract
We present a visual study of the convergence of the Parallel Transported Multigrid (PTMG) in the presence of Atyiah-Singer lattice zero modes. In particular, we explain the differences in the behavior of various PTMG variants and the divergence of the standard PTMG algorithm at nonphysically small masses m. To check our understanding we predict and verify at m = 0 a quite dramatic dependence of the convergence on the instanton size modulo 4.
