HNN-扩张共轭问题的通有复杂性与Miller群的算法分层
Generic complexity of the Conjugacy Problem in HNN-extensions and algorithmic stratification of Miller's groups
摘要:
本文讨论了群的HNN-扩张中共轭问题的时间复杂性,特别是在Miller群中。我们表明,“几乎所有”,在某种明确的意义上,元素,共轭问题是在立方时间可判定的。值得注意的是,米勒群中的共轭问题可能是不可判定的。我们的研究结果表明,“硬”的问题的情况下,包括一个可以忽略不计的一小部分组。
英文摘要:
We discuss time complexity of The Conjugacy Problem in HNN-extensions of groups, in particular, in Miller's groups. We show that for "almost all", in some explicit sense, elements, the Conjugacy Problem is decidable in cubic time. It is worth noting that the Conjugacy Problem in a Miller group may have be undecidable. Our results show that "hard" instances of the problem comprise a negligibly small part of the group.
