Systems of generators for normalizers of some elements of a braid group. (Russian) Zbl 0548.20022
The author determines the normalisers of the following elements in the braid group \(B_{n+1}: \sigma_{i,j}=\sigma_ i\sigma_{i+1}...\sigma_ j, \tau_{j,i}=\sigma_ j\sigma_{j- 1}...\sigma_ i, (\sigma_{i,j}\tau_{j,i})^ t\) and \((\tau_{j,i}\sigma_{i,j})^ t\) and \((\sigma_{i,j}\sigma_{i,j- 1}...\sigma_{i,i})^ t,\) where 1\(\leq i\leq j\leq n\) and t is a positive integer. The results are too complicated to give here.
