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…

On the 3- $γ_{t}$ -Critical Graphs of Order $Δ (G) + 3$

Haoli Wang, Xirong Xu, Yang Yuansheng +1

Let $γ_{t} (G)$ be the total domination number of graph $G$ , a graph $G$ is $k$ -total domination vertex critical (or\ just\ $k$ - $γ_{t}$ -critical) if $γ_{t} (G) = k$ , and for any vertex $v$ o…
