Detecting Prime Numbers via Roots of Polynomials
Dobbs, David E.
International Journal of Mathematical Education in Science and Technology, v43 n3 p381-387 2012
It is proved that an integer n [greater than or equal] 2 is a prime (resp., composite) number if and only if there exists exactly one (resp., more than one) nth-degree monic polynomial f with coefficients in Z[subscript n], the ring of integers modulo n, such that each element of Z[subscript n] is a root of f. This classroom note could find use in any introductory course on abstract algebra or elementary number theory.
