Random polynomials over a finite field

  • G. I. Ivchenko and Yu. I. Medvedev

Abstract

We consider monic (with higher coefficient 1) polynomials of fixed degree n over an arbitrary finite field GF(q), where q ≥ 2 is a prime number or a power of a prime number. It is assumed that on the set Fn ={ƒn} of all qn such polynomials the uniform measure is defined which assigns the probability q-n to each polynomial. For an arbitrary polynomial ƒnFn, its local structure Kn = K(ƒn) is defined as the set of multiplicities of all irreducible factors in the canonical decomposition of ƒn, and various structural characteristics of a polynomial (its exact and asymptotic as n → ∞ distributions) which are functionals of Kn are studied. Directions of possible further research are suggested.
