Let denote the space of oriented knots in an oriented and be any abelian group. Then, given any invariant , we can extend to -singular knots (i.e. knots with one double point) by setting:
- Failed to parse (unknown function "\doublepoint"): {\displaystyle V^{(1)}(\doublepoint)=V(\overcrossing) - V(\undercrossing)}
