SESAM and TXL Results for Wilson Action--A Status Report
, 1997 Results from two studies of full QCD with two flavours of dynamical Wilson fermions are presented. At beta=5.6, the region 0.83 > m_pi/m_rho > 0.56 at m_pia > 0.23 L^{-1} is explored.

The shifted classical circulant and skew circulant splitting iterative methods for Toeplitz matrices [PDF]
, 2017 It is known that every Toeplitz matrix T enjoys a circulant and skew circulant splitting (denoted by CSCS), i.e., T=C-S with C a circulant matrix and S a skew circulant matrix. Based on the variant of such a splitting (also referred to as CSCS),
