Towards Multigrid Methods for Propagators of Staggered Fermions with Improved Averaging and Interpolation Operators

Thomas Kalkreuter

A Dirac choice for the averaging kernel is implemented numerically. This improved kernel will be needed in gauge covariant multigrid computations for propagators of staggered f…

Idealized Multigrid Algorithm for Staggered Fermions

Thomas Kalkreuter

An idealized multigrid algorithm for the computation of propagators of staggered fermions is investigated. Exemplified in four-dimensional gauge fields, it is shown that th…
