  "abstract": "We lay out the analysis of the ``Kronecker preconditioners'' adopted in [24] for the linear wave equations. Importantly, we deliver the analysis justifying the claims in~[24, Section 4.2] about these preconditioners and we unpack all of the necessary numerical background for a full understanding of the observed phenomena.",
