PL homeomorphisms of surfaces and codimension $2$ PL foliations

Sam Nariman

Haefliger-Thurston's conjecture predicts that Haefliger's classifying space for $C^{r}$ -foliations of codimension $n$ whose normal bundles are trivial is $2 n$ -connected. In this pape…

The free factor complex and the dualizing module for the automorphism group of a free group

Zachary Himes, Jeremy Miller, Sam Nariman +1

Answering a question of Hatcher-Vogtmann, we prove that the top homology group of the free factor complex is not the dualizing module for $Aut (F_{n})$ , at least for $n = 5$ .

On flat manifold bundles and the connectivity of Haefliger's classifying spaces

Sam Nariman

We investigate a conjecture due to Haefliger and Thurston in the context of foliated manifold bundles. In this context, Haefliger-Thurston's conjecture predicts that every $M$ -bund…
