On the relative Lusternik-Schnirelmann category with respect to a closed 1-form
Tieqiang Li, Dirk Schuetz
In this article we study a homotopy invariant cat(X,B,ξ) on a pair of finite CW complexes with respect to a continuous closed 1-form. This is a generalisation of a Lusternik-Schnir…

Closed 1-Forms in Topology and Geometric Group Theory
Michael Farber, Ross Geoghegan, Dirk Schuetz
In this article we describe relations of the topology of closed 1-forms to the group theoretic invariants of Bieri-Neumann-Strebel-Renz. Starting with a survey, we extend these Sig…

Homology of planar polygon spaces
Michael Farber, Dirk Schuetz
In this paper we study topology of the variety of closed planar polygons with given side lengths. We describe the Betti numbers of the moduli spaces as functions of the length vect…
