Krylov space solvers for shifted linear systems
B. Jegerlehner
We investigate the application of Krylov space methods to the solution of shifted linear systems of the form (A+σ) x - b = 0 for several values of σsimultaneously, using only as ma…

Some aspects of simulation algorithms for dynamical fermions
Karl Jansen, Beat Jegerlehner, Chuan Liu
Three topics concerning fermion simulation algorithms are discussed: 1.) A performance comparison of the multiboson technique to simulate dynamical fermions and the Kramers equatio…
