    Description
    It has recently become clear that chiral symmetry can be exactly preserved in lattice gauge theory, without violating fundamental principles or having more fermions than intended. As a result it is now possible to set up chiral gauge theories on the lattice in a theoretically appealing way. Particular attention will be paid to the cancellation of the anomaly and its interpretation in terms of local cohomology.
