Title: The Novikov homology and complex hyperplane arrangements
Date: Thu, Dec 01, 2011, 15:30 - 17:00
Place: Seminar Room B
Abstract: We begin with a brief survey of the Novikov homology and its applications to to the topology of circle-valued Morse functions
and more generally, closed 1-forms.
In the second part of the talk we show that
for an essential arrangement in an n-dimensional complex vector space the Novikov homology of its complement vanishes in all degrees except n.
This is a joint work with Toshitake Kohno.
