Abstract:We survey aspects of classical combinatorial sutured manifold theory and show how they can be adapted to study exceptional Dehn fillings and 2-handle additions. As a consequence we show that if a hyperbolic knot β in a compact, orientable, hyperbolic 3-manifold M has the property that winding number and wrapping number are not equal with respect to a non-trivial class in H 2 (M, ∂ M), then, with only a few possible exceptions, every 3-manifold M ′ obtained by Dehn surgery on β with surgery distance ∆ ≥ 2 will … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
