CONFERENCE IN HONOUR OF PETER ORLIK
to be held at the Fields Institute

OVERVIEW
Peter Orlik's work has been influential for a particularly broad
mathematical community: his seventy-some publications to date include
five books, and his focus has included Seifert manifolds, singularities,
reflection groups and invariant theory, braids, hyperplane arrangements,
and hypergeometric integrals. The theory of hyperplane arrangements
should receive special mention since, together with Hiroaki Terao
and Louis Solomon, Peter Orlik pioneered the area and established
many of the foundational results. In doing so, they constructed
a fertile meeting point for algebra, topology, and combinatorics.
The aim of this conference is to bring together individuals in some
of the various areas interconnected by Peter’s legacy. This
is both to facilitate ongoing collaborations in some of the most
exciting areas spawned by his work, and also to encourage new relationships
between specialists with hitherto undiscovered common ground. In
particular, we hope to attract a good number of graduate students
and recent PhDs both from Ontario and further afield.
