A new approach to the genus spectra of abelian $p$ -groups

Haimiao Chen, Yang Li

Given a finite group $G$ , the {\it genus spetrum} $sp (G)$ of $G$ is the set of integers $g \geq 0$ such that $G$ can act faithfully on an orientable closed surface of genus $g…

Solving the isomorphism problems for two families of parafree groups

Haimiao Chen

For any integers $m, n$ with $m \neq = 0$ and $n > 0$ , let $G_{m, n}$ denote the group presented by $⟨ x, y, z ∣ x = [z^{m}, x] [z^{n}, y]⟩$ ; for any integers $m, n > 0$ , let $H_{m, n}$ den…

Finite $p$ -groups of class $2$ as central extensions

Haimiao Chen

Finite $p$ -groups of nilpotency class 2 are treated from the perspective of central extensions. Given finite abelian groups $G, A$ , we derive an explicit formula for cocycles repres…

Automorphisms of metacyclic groups

Haimiao Chen, Yueshan Xiong, Zhongjian Zhu

A metacyclic group $H$ can be presented as $⟨ α, β ∣ α^{n} = 1, β^{m} = α^{t}, β α β^{- 1} = α^{r} ⟩$ for some $n, m, t, r$ . Each endomorphism $σ$ of $H$ is determined by $σ(α)…
