Using orthogonal projectors in multigrid multilevel Monte Carlo for trace estimation in lattice QCD

Andreas Frommer, Jose Jimenez-Merchan, Francesco Knechtli +2

We introduce a multigrid multilevel Monte Carlo method for stochastic trace estimation in lattice QCD based on orthogonal projections. This formulation extends the previously propo…
