Boundary slopes (nearly) bound cyclic slopes

Thomas W. Mattman

Abstract. Let r_m and r_M be the least and greatest finite boundary slopes of a hyperbolic knot K in S^3. We show that any cyclic surgery slopes of K must lie in the interval (r_m - 1/2, r_M + 1/2).

Keywords. Dehn surgery, character variety, exceptional surgery, boundary slope
