On Finite Groups with Element Order Set of Width 3

Eric Min, Chloe So, Yong Yang +3

We study finite groups in which every element order is divisible by at most three distinct primes. We determine the possible nonabelian composition factors, prove that a nonabelian…

On The Largest Character Degree And Solvable Subgroups Of Finite Groups

Zongshu Wu, Yong Yang

Let $G$ be a finite group, and $π$ be a set of primes. The $π$ -core $O_{π} (G)$ is the unique maximal normal $π$ -subgroup of $G$ , and $b (G)$ is the largest irreducible charac…

Huppert's analogue conjecture for $\PSL(3,q)$ and $\PSU(3,q)$

Yang Liu, Yong Yang

Let $G$ be a finite group and $χ\in \irr(G)$. The codegree of $χ$ is defined as $\cod(χ)=\frac{|G:\ker(χ)|}{χ(1)}$ and $\cod(G)=\{\cod(χ) \ |\ χ\in \irr(G)\}$ is called the set of…
