The reducibility theorem for linearised polynomials over finite fields
Stephen D. Cohen · Bulletin of the Australian Mathematical Society · 1989
A self-contained elementary account is given of the theorem of S. Agou that classifies all composite irreducible polynomials of the form over a finite field of characteristic p. Written to appeal to a wide readership, it is intended to complement the original rather technical proof and other contributions by the author and by Moreno.
