辫群抛物子群的双陪集问题

The double coset problem for parabolic subgroups of braid groups

Bar-Ilan University(巴伊兰大学)

Arkadius Kalka, Mina Teicher, Boaz Tsaban

AI总结:

针对辫群中所有具有连通Coxeter图的抛物子群,首次给出双陪集问题的解,并推广至所有抛物子群。

摘要:

我们首次为辫群的一大类自然子群(即所有具有连通关联Coxeter图的抛物子群)提供了双陪集问题(DCP)的解。更新:我们成功解决了辫群所有抛物子群的DCP。

英文摘要:

We solve the double coset problem for arbitrary parabolic subgroups of the $n$-strand braid group $B_n$, by reducing it to the simultaneous conjugacy problem in the larger group $B_{n+1}$. The resulting decision algorithm is uniform in the braid index and the supplied subgroup generators. We also formulate the reduction for general group embeddings, and apply it to additional commuting constraints, several other spherical Artin types, and finite direct products.
