A combinatorial theory for well-generated complex reflection groups
Coxeter systems are extremely powerful tools in the study of finite real
reflection groups, their associated braid groups and many related objects.
Coxeter theory does not generalise to complex reflection groups, but there
exists an alternate theory, providing an effective substitute applicable to
a wide class of complex reflection groups. We will describe the main
features of this new combinatorial theory, as well as some topological
applications.
