Irreducible compositions of degree two polynomials over finite fields have regular structure

Let q be an odd prime power and D be the set of irreducible polynomials in Fq[x] which can be written as a composition of degree two polynomials. In this paper we prove that D has a natural regular structure by showing that there exists a finite automaton having D as accepted language. Our method is...

description Let q be an odd prime power and D be the set of irreducible polynomials in Fq[x] which can be written as a composition of degree two polynomials. In this paper we prove that D has a natural regular structure by showing that there exists a finite automaton having D as accepted language. Our method is constructive.
