Computing ,(,), for Matrix Functions t applies quadrature to the matrix version of the Cauchy integral theorem. Methods specific to the logarithm, based on quadrature, and fractional matrix powers, based on solution of an ordinary differential equation initial value problem, are also presented

Reversibility and Instabilities in Hybrid Monte Carlo Simulationss. In this contribution we review pedagogically where these instabilities arise, how they may be noticed and what actions can be taken to avoid them. The discussion is of relevance to simulations with light quarks such as those attainable using Ginsparg Wilson fermions.

The Nucleon Mass in Chiral Effective Field Theoryariation of QCD observables. Considering a range of regularisation schemes, we study both the expansion of the nucleon mass about the chiral limit and the practical application a of extrapolation for modern lattice QCD.

Fast Evaluation of Zolotarev Coefficients-geometric mean allows us to evaluate elliptic functions cheaply, and thus to compute Zolotarev coefficients “on the fly” as a function of ε. This in turn allows us to calculate the matrix functions sgn., ., and . both quickly and accurately for any Hermitian matrix . whose spectrum lies in the specified range.

The Overlap Dirac Operator as a Continued Fractionthin this formulation the inverse of the overlap operator can be calculated by a single Krylov space method and nested conjugate gradient procedures are avoided. We point out that the five dimensional linear system can be made well conditioned using equivalence transformations on the continued fractions.
