High Quality Content by WIKIPEDIA articles! In the mathematical field of knot theory, the unlink is a link that is equivalent to finitely many disjoint circles in the plane. In mathematics, knot theory is the area of topology that studies mathematical knots. While inspired by knots which appear in daily life in shoelaces and rope, a mathematician's knot differs in that the ends are joined together to prevent it from becoming undone. In precise mathematical language, a knot is an embedding of a circle in 3-dimensional Euclidean space. Two mathematical knots are equivalent if one can be transformed into the other via a deformation of R3 upon itself; these transformations correspond to manipulations of a knotted string that do not involve cutting the string or passing the string through itself.
