Let be the space in which a knot sits. Then the space "around" the knot, i.e., everything but the knot itself, is denoted and is called the knot complement of (Adams 1994, p. 84).
If a knot complement is hyperbolic (in the sense that it admits a complete Riemannian metric of constant Gaussian curvature ), then this metric is unique (Prasad 1973, Hoste et al. 1998).
