Abstract

A Dirac choice for the averaging kernel $C$ is implemented numerically. This improved kernel will be needed in gauge covariant multigrid computations for propagators of staggered fermions. Results for $C$ and the variational coarse grid operator will be given in 2- $d$ $SU(2)$ gauge fields. C++ is advocated for future algorithm development.
