The uniqueness of vertex pairs in $π$ -separable groups

Lei Wang, Ping Jin

Let $G$ be a finite $π$ -separable group, where $π$ is a set of primes, and let $χ$ be an irreducible complex character that is a $π$ -lift of some $π$ -partial character of $G$ .It wa…

Codegrees of primitive characters of solvable groups

Ping Jin, Lei Wang, Yong Yang

We obtain the codegree of a certain primitive character for a finite solvable group, and thereby give a negative answer to a question proposed by Moretó in \cite{Moreto}.

A note on larger orbit size

Jin Ping, Yong Yang

In this note, we present an improvement on the large orbit result of Halasi and Podoski, and then answer an open question raised by Chen, Cossey, Lewis, and Tong-Viet.
