Dynamics and the Godbillon-Vey Class of C^1 Foliations
Steven Hurder, Rémi Langevin
Let F be a codimension-one, C^2-foliation on a manifold M without boundary. In this work we show that if the Godbillon--Vey class GV(F) \in H^3(M) is non-zero, then F has a hyperbo…

The Equivariant LS-Category of Polar Actions
Steven Hurder, Dirk Toeben
We will provide a lower bound for the equivariant Lusternik-Schnirelmann category of an arbitrary proper action in terms of the stratification by orbit types, and an upper bound fo…

Transverse LS-Category for Riemannian Foliations
Steven Hurder, Dirk Toeben
We study the transverse Lusternik-Schnirelmann category of a Riemannian foliation on a compact manifold. We obtain a necessary and sufficient condition when the transverse LS categ…
