MS5
Linear Systems and Matrix Functions in Computational Theoretical Physics

10:30 AM - 12:30 PM
Room: Oak Alley - 3rd Floor

This minisymposium deals with computations arising in lattice simulations, such as QCD and nuclear lattice simulations. The minisymposium will be of interest to numerical analysts, theoretical physicists as well as computational scientists. We will focus in particular on the solution of systems of linear equations and matrix functions that arise in these simulations.

The purpose of this minisymposium is to offer a platform for the exchange of key ideas between lattice simulations and numerical linear algebra. The first talk explains the physics background and the particular computational challenges in QCD simulations. The subsequent talks will focus on specific problems involving the solution of sparse linear systems and determinant computations.
