Doubled Knot


DoubledKnot

Let K be the knot above, and let the homomorphism h taking a knot K_1 to its companion knot K_2 be faithful (i.e., taking the preferred longitude and meridian of the original torus to the referred longitude and latitude of the tubular neighborhood). Then K_2 is an untwisted doubled knot of K_1. Otherwise, K_2 is a doubled knot with q twists (Rolfsen 1976, p. 112).
