Spin characters of the alternating group which are proportional to linear characters in characteristic 2

Eoghan McDowell

We classify when a spin and a non-spin irreducible character of the alternating group have proportional 2-modular reductions. Equivalently, we classify when such a pair of characte…

Spin characters of symmetric and alternating groups which are proportional in characteristic 3

Matthew Fayers, Eoghan McDowell

Let be a finite group and a prime. It is interesting to determine when two ordinary irreducible representations of have the same -modular reduction; this is the same…
