linkinvariants
Link invariants are mathematical quantities associated with a link in three-dimensional space that remain unchanged under ambient isotopy. An ambient isotopy is a continuous deformation of the surrounding space that does not self-intersect, and thus preserves the topological structure of the link. This means that if two links can be smoothly deformed into one another without cutting or passing through themselves, they will have the same link invariants.
The primary purpose of link invariants is to distinguish between different links. If two links have different
Several types of link invariants exist, ranging from simple scalar values to more complex algebraic structures.
