Abstract:
Closed essential surfaces in a 3–manifold can be detected by ideal points of the character variety or by algebraic non-integral representations. We give examples of closed essential surfaces not detected in either of these ways. For ideal points, we use Chesebro’s module-theoretic interpretation of Culler-Shalen theory. As a corollary, we construct an infinite family of closed hyperbolic Haken 3–manifolds with no algebraic non-integral representation into $\textrm {PSL}_2 (\mathbb {C})$, resolving a question of Schanuel and Zhang.References
