ABSTRACT: The
Artin groups are certain finitely presented groups associated to a
labeled simplicial graph. The generators correspond to the vertices and
the relations to the labeled edges. These relations are those satisfied
in the local fundamental group of a plane curve singularity of cuspidal
type. It seems thus natural to inquire whether the Artin groups are
fundamental groups of complements to projective plane curves. We
address this question in the talk making use of group invariants of
Alexander type.
