AN INTRODUCTION TO LATTICE CHIRAL FERMIONS
Monday, 30 June, 11:15
Abstract: This introduction will focus on two topics: The first deals with the basic mathematical aspects of lattice chirality; the second, with practical implementation. For both topics a brief overview will be given, followed up by the presentation of a new and yet unexplored idea.

MONTE CARLO ALGORITHMS FOR QCD
Monday, 30 June, 09:30
Abstract: An introduction to the simulation technology used in current Monte Carlo simulations of QCD with dynamical fermions is presented. The Markov processes used to generate an ensemble of gauge field configurations are described and some of the key problems and bottlenecks are outlined. Current research directions are then discussed.

QCD FOR NUMERICAL ANALYSTS
Monday, 30 June, 14:00
Abstract: The purpose of this talk is to present those topics and objects in lattice QCD which are important to understand the numerical analysis challenges in computations in QCD simulations. We will discuss the Wilson-Fermion matrix in some detail, then turn to progress in recent years due to improved techniques from numerical linear algebra and finally review the current challenges for the simulation of Neuberger fermions.

COMPUTATIONAL METHODS FOR CHIRAL FERMIONS
Monday, 30 June, 15:45
Abstract: I describe properties of chiral fermion operators and methods to implement it numerically. I use the results from the spectral flow of the operator to illuminate the difficulties in practical implementations of chiral fermions. I will describe related variants of chiral fermions that attempt to avoid these difficulties. Numerical methods for both quenched and dynamical methods will also be given.
