Given any finite group G and any prime p, it is interesting to ask which ordinary irreducible representations of G remain irreducible in characteristic p. This question was solved for the symmetric groups several years ago, by the speaker and others. Here we address the case of the alternating group when p is odd. We’ll translate the question to one about representations of the symmetric group, and then explain how to answer it.
