Prof. Masahiko Yoshinaga (Hokkaido University): Characteristic polynomials of hyperplane arrangements

Academic or specialist Colloquium / Congress / Forum

The characteristic polynomial of a hyperplane arrangement
is related to many counting problems. In the first half of this
talk, I will give an overview of several aspects of the
characteristic polynomial. Then I will focus on the relationship
with lattice points counting and Eulerian polynomials, in
connection with a conjecture by Postnikov and Stanley on
the location of roots of the characteristic polynomial of
certain arrangements.
