Conway skein equivalence
From Encyclopedia of Mathematics
An equivalence relation on the set of links in (cf. also Link). It is the smallest equivalence relation on ambient isotopy classes of oriented links, denoted by , that satisfies the following condition: If and are Conway skein triples (cf. also Conway skein triple) such that if and then , and, furthermore, if and then .
Skein equivalent links have the same Jones–Conway polynomials (cf. also Jones–Conway polynomial) and the same Murasugi signatures (for links with non-zero determinant, cf. also Signature). The last property generalizes to Tristram–Levine signatures.
