Английская Википедия:Algebraic link
Материал из Онлайн справочника
In the mathematical field of knot theory, an algebraic link is a link that can be decomposed by Conway spheres into 2-tangles.[1] Algebraic links are also called arborescent links.[2] Although algebraic links and algebraic tangles were originally defined by John H. Conway as having two pairs of open ends, they were subsequently generalized to more pairs.[3]
