p-群的非交换张量平方及相关构造

Non-abelian tensor square and related constructions of $p$-groups

Raimundo Bastos, Emerson de Melo, Nathália Gonçalves, Ricardo Nunes

AI总结:

针对p-群,定义其非交换张量平方的G×G扩张ν(G),证明有限幂p-群的非交换张量平方及ν(G)下中心列项的幂嵌入性、幂p-群ν(G)的指数性质,并研究幂p-群的弱交换构造。

摘要:

设G为群,用ν(G)表示非交换张量平方[G,G^φ]由G×G得到的某种扩张。证明:若G是有限幂p-群,则[G,G^φ]和下中心列的第k项γ_k(ν(G))在ν(G)中幂嵌入(定理A);若G是幂p-群,则ν(G)的指数exp(ν(G))整除p·exp(G)(定理B);还研究了幂p-群的弱交换构造(定理C)。

英文摘要:

Let $G$ be a group. We denote by $ν(G)$ a certain extension of the non-abelian tensor square $[G,G^φ]$ by $G \times G$. We prove that if $G$ is a finite potent $p$-group, then $[G,G^φ]$ and the $k$-th term of the lower central series $γ_k(ν(G))$ are potently embedded in $ν(G)$ (Theorem A). Moreover, we show that if $G$ is a potent $p$-group, then the exponent $\exp(ν(G))$ divides $p \cdot \exp(G)$ (Theorem B). We also study the weak commutativity construction of powerful $p$-groups (Theorem C).
