Abstract: | We say that is a characterizing slope for a knot in the 3-sphere if the oriented homeomorphism type of -surgery is sufficient to determine the knot uniquely. I will discuss the problem of determining which slopes are characterizing for torus knots, paying particular attention to non-integer slopes. This problem is related to determining which knots in have Seifert fibered surgeries. |
