摘要

Let F be a field of prime characteristic p containing F-pn as a subfield. We refer to q(X) = X-pn - X - a is an element of F[X] as a generalized Artin-Schreier polynomial. Suppose that q(X) is irreducible and let C-q(X) be the companion matrix of q(X). Then ad C-q(X) has such highly unusual properties that any A is an element of gl(m) such that ad A has like properties is shown to be similar to the companion matrix of an irreducible generalized Artin-Schreier polynomial. We discuss close connections with the decomposition problem of the tensor product of indecomposable modules for a one-dimensional Lie algebra over a field of characteristic p, the problem of finding an explicit primitive element for every intermediate field of the Galois extension associated to an irreducible generalized Artin-Schreier polynomial, and the problem of finding necessary and sufficient conditions for the irreducibility of a family of polynomials.
