One dimensional non-Hausdorff manifolds and foliations of the plane
André Haefliger, Georges Reeb
The original article titled "Variétés (non séparées) à une dimension et structures feuilletées du plan" was published in 1957 in French in L'Enseignement Mathématique. It establish…
On locally trivial extensions of topological spaces by a pseudogroup
Andre Haefliger, Ana Maria Porto F. Silva
In this paper we restrict ourselves to the particular case where the pseudogroup is given by the action of a dense subgroup of a Lie group acting on by lef…
On the space of morphisms between étale groupoids
André Haefliger
Given two étale groupoids $\Cal G$ and $\Cal G'$, we consider the set of pointed morphisms from $\Cal G$ to $\Cal G'$. Under suitable hypothesis we introduce on this set a structur…
Closed geodesics on orbifolds
K. Guruprasad, A. Haefliger
In this paper, we try to generalize to the case of compact Riemannian orbifolds some classical results about the existence of closed geodesics of positive length on compact Rie…
