On Zappa's question in the case of alternating groups

Ru Zhang, Rulin Shen

In 1962, Guido Zappa asked whether a non-trivial coset of a Sylow $p$ -subgroup of a finite group could contain only elements whose orders are powers of $p$ . Marston Conder gives a…

On Thompson Problem

Rulin Shen, Wujie Shi, Feng Tang

In 1987, the second author of this paper reported his conjecture, all finite simple groups $S$ can be characterized uniformly using the order of $S$ and the set of element orders i…

Finite groups in which every maximal subgroup is nilpotent or normal or has $p^{'}$ -order

Jiangtao Shi, Na Li, Rulin Shen

Let $G$ be a finite group and $p$ a fixed prime divisor of $∣ G ∣$ . Combining the nilpotence, the normality and the order of groups together, we prove that if every maximal subgroup…

The second minimum/maximum value of the number of cyclic subgroups of finite $p$ -groups

Mihai-Silviu Lazorec, Rulin Shen, Marius Tărnăuceanu

Let $C (G)$ be the poset of cyclic subgroups of a finite group $G$ and let $P$ be the class of $p$ -groups of order $p^{n}$ ( $n \geq 3$ ). Consider the function $α:\mathcal{P}\…
