On \(n\)-equivalence of knots and invariants of finite degree. (Russian. English summary) Zbl 0824.57002
Summary: A notion of \(n\)-equivalence of knots is introduced and it is shown that the equivalence classes with the connected sum operation make finitely generated abelian groups composing an inverse sequence. The \(n\)- equivalence class of knot is the universal invariant of degree \(n\) (Vassiliev invariant).
