Abstract

Let
be a finitely generated group. To every generating set
of
and every complex finite dimensional representation
of
, we
associate the determinantal hypersurface
where
is the
identity operator, and we investigate how the geometry of this hypersurface reflects the properties of
. In the classical case when
is a finite Coxeter group
of regular type and
is a
Coxeter generating set for
we show that
determines
