Lattice Fermions and Structure of the Vacuum

Written versions of the 38 talks and poster presentations at an October 1999 workshop in Dubna, Russia look at two key problems in modern field theory: the formulation of chiral gauge theories on the lattice, and the quantitative understanding of the quark confinement mechanism. The two are linked by the topological origin of both the chiral nature of the fermions and the confining forces. The topics include domain-wall fermions in vector theories, optimizing chirality and scaling lattice fermions, a new multi-boson algorithm proposed by Slavnov, preliminary results with lattice covariant gauge, classical solutions and the vacuum structure in lattice gauge theories, vortices and confinement, some pieces of lattice evidence in favor of the center-vortex picture of color confinement, chirality carried by monopoles, and random matrix theory and Dirac spectrum at non-zero temperatures and density.
