The classification of partially symmetric 3-braid links

Alexander Stoimenov (2015)

Open Mathematics

Similarity:

We classify 3-braid links which are amphicheiral as unoriented links, including a new proof of Birman- Menasco’s result for the (orientedly) amphicheiral 3-braid links. Then we classify the partially invertible 3-braid links.

Flat hierarchy

Vassily O. Manturov (2005)

Fundamenta Mathematicae

Similarity:

We consider the hierarchy flats, a combinatorial generalization of flat virtual links proposed by Louis Kauffman. An approach to constructing invariants for hierarchy flats is presented; several examples are given.
