Some Answered and Unanswered Questions about the Structure of the Set of Fermionic Actions with GWL became popular topics in lattice field theory. Most of these issues are not resolved to my satisfaction (if at all), which actually makes them an appropriate material to discuss at a workshop like this.

CONE

Regularization and Anomalies in Gauge Theory,in lattice gauge theory. The generalized Pauli-Villars regularization is discussed from a view point of the covariant regularization of currents, and the construction of a regularized effective action in terms of covariant currents is compared with the lattice formulation of chiral Abelian theory.

Chiral Symmetry Outside Perturbation Theory,ries. My main objective is to clear up an unhealthy confusion about how many successful approaches to regulate chiral fermions on the lattice there really are: At the moment, there is only one, the overlap, and finding a genuinely different approach is an important and completely open problem.

Abelian and Nonabelian Lattice Chiral Gauge Theories Through Gauge Fixing,ical evidence that abelian lattice chiral gauge theories can be nonperturbatively constructed through the gauge-fixing approach. In addition, we indicate how we believe that the method may be extended to nonabelian chiral gauge theories.

Better Domain-Wall Fermions,We discuss two modifications of domain-wall fermions, aimed to reduce the chiral-symmetry violations presently encountered in numerical simulations.
