Given a group G and an automorphism φ of G, two elements are said to be φ-conjugate if for some . The number of equivalence classes is the Reidemeister number of φ, and if for all automorphisms of G, then G is said to have the -property.
A finite simple graph Γ gives rise to the right-angled Artin group , which has as generators the vertices of Γ and as relations if and only if v and w are joined by an edge in Γ. We conjecture that all non-abelian right-angled Artin groups have the -property and prove this conjecture for several subclasses of right-angled Artin groups.

在[R ∞ -特性为直角阿廷组
给定的一组G ^和构φ的ģ,两个元件被称为φ-共轭 对于一些 。等价类的数量是Reidemeister数的φ,如果对于G的所有自同构,则称G具有-属性。
有限简单图Γ引起直角Artin组 ,它具有Γ的顶点和关系 当且仅当v和w通过Γ中的边连接时。我们推测所有非阿贝尔直角阿丁族群都有属性,并证明对直角Artin组的几个子类的猜想。
