Surgery obstructions and character varieties

Steven Sivek, Raphael Zentner

We provide infinitely many rational homology 3-spheres with weight-one fundamental groups which do not arise from Dehn surgery on knots in $S^{3}$ . In contrast with previously known…

A menagerie of SU(2)-cyclic 3-manifolds

Steven Sivek, Raphael Zentner

We classify $S U (2)$ -cyclic and $S U (2)$ -abelian 3-manifolds, for which every representation of the fundamental group into $S U (2)$ has cyclic or abelian image respectively, among geo…
