Abstract:
Sufficient conditions for a closed $n$-braid $\widehat {\beta }$ to have infinite sets ${\mathfrak {D}}(\widehat {\beta })$ and ${\mathfrak {S}}(\widehat {\beta })$ are given, where ${\mathfrak {D}}(\widehat {\beta })$ denotes the set of all closed $(n-1)$-braids that are obtained from $\widehat {\beta }$ via Markov destabilization, while ${\mathfrak {S}}(\widehat {\beta })$ denotes the set of all closed $(n+1)$-braids that are obtained from $\widehat {\beta }$ via Markov stabilization. New integer-valued conjugacy invariants for the braid group are introduced.References
