Cusp types covered by hyperbolic knot complements
Neil Hoffman, Oklahoma State
[Abstract] [PDF]
Abstract: Let $Q$ be an orbifold quotient of a hyperbolic knot complement. This talk will give a complete classification of the types of cusps $Q$ can admit. In particular, we will show that $Q$ does not have a $S^2(2,4,4)$ cusp. We will also discuss the non-orientable case and the connection between this problem and the question of which knots admit hidden symmetries.
