|Place:||Seminar Room B|
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.
