Navarro vertices and lifts in solvable groups

Lei Wang, Ping Jin

Let $Q$ be a $p$ -subgroup of a finite $p$ -solvable group $G$ , where $p$ is a prime, and suppose that $δ$ is a linear character of $Q$ with the property that $δ (x) = δ (y)$ whenever $x…

Lifts of Brauer characters in characteristic two

Ping Jin, Lei Wang

A conjecture raised by Cossey in 2007 asserts that if $G$ is a finite $p$ -solvable group and $φ$ is an irreducible $p$ -Brauer character of $G$ with vertex $Q$ , then the number of l…
