In mathematical Knot Theory , the Hopf link, named after Heinz Hopf , is the simplest nontrivial Link with more than one component. It consists of two Circle s linked together exactly once. For a concrete model take the Unit Circle in the ''xy''-plane centered at the origin and another unit circle in the ''yz''-plane centered at (0,1,0). Depending on the relative Orientation s of the two components the Linking Number of the Hopf link is ±1. The Hopf link is a (2,2)- Torus Link with the Braid Word : In the Hopf Bundle : the fibers over any two distinct points in form a Hopf link in the 3-sphere . EXTERNAL LINKS
