A construction of two distinct canonical sets of lifts of Brauer characters of a p-solvable group

James P. Cossey

Navarro defined the set $I r r (G ∣ Q, δ) \subseteq I r r (G)$ , where $Q$ is a $p$ -subgroup of a $p$ -solvable group $G$ , and shows that if $δ$ is the trivial character of $Q$ , the…

Bounds on the number of lifts of a Brauer character in a p-solvable group

James P. Cossey

The Fong-Swan theorem shows that for a $p$ -solvable group $G$ and Brauer character $ϕ\in \ibrg$, there is an ordinary character $χ\in \irrg$ such that $χ^{0} = ϕ$ , where $^{0}$ denotes…
