[Homotopical multicrossing complex ] И. М. Никонов |
|||
|
Аннотация: We introduce the multicrossing complex of a tangle and define the crossing homology class. In a sense, the multicrossing complex unifies tribracket, biquandle and crossoid homologies; and the tribracket, biquandle and crossoid cycle invariants are actually the result of pairing a tribracket (biquandle, crossoid) cocycle with the crossing homology class.
