Tangle (mathematics)
text:
In mathematics, a tangle is generally one of two related concepts: In John Conway's definition, an n-tangle is a proper embedding of the disjoint union of n arcs into a 3-ball; the embedding must send the endpoints of the arcs to 2n marked points on the ball's boundary.
In link theory, a tangle is an embedding of n arcs and m circles into R 2 × [ 0 , 1 ] – the difference from the previous definition is that it includes circles as well as arcs, and partitions the boundary into two (isomorphic) pi
