Irreducible restrictions of Brauer characters of the Chevalley group G_2(q) to its proper subgroups

Hung Ngoc Nguyen

Let $G_{2} (q)$ be the Chevalley group of type $G_{2}$ defined over a finite field with q=p^n elements, where p is a prime number and $n$ is a positive integer. In this paper, we determ…

Cross characteristic representations of $^{3} D_{4} (q)$ are Reducible over proper subgroups

Hung Ngoc Nguyen, Pham Huu Tiep

We prove that the restriction of any absolutely irreducible representation of Steinberg's triality groups $^{3} D_{4} (q)$ in characteristic coprime to q to any proper subgroup is reduci…

Low-dimensional complex characters of the symplectic and orthogonal groups

Hung Ngoc Nguyen

We classify the irreducible complex characters of the symplectic groups $S p_{2 n} (q)$ and the orthogonal groups $S p i n_{2 n}^{\pm} (q)$ , $S p i n_{2 n + 1} (q)$ of degrees up to the bound D, wh…

On the restriction of cross characteristic representations of ^2F_4(q) to proper subgroups

Frank Himstedt, Hung Ngoc Nguyen, Pham Huu Tiep

We prove that the restriction of any nontrivial representation of the Ree groups $^{2} F_{4} (q), q = 2^{2 n + 1} \geq 8$ in odd characteristic to any proper subgroup is reducible. We also de…
