WebMore generally, we have the following: Theorem: Let f ( x) be a polynomial over Z p of degree n . Then f ( x) has at most n roots. Proof: We induct. For degree 1 polynomials a x + b, we … WebNow note, if α is a root of f(x) mod p then plug in to get . α. p. − α = f(α)g(α) + r(α) ≡ 0g(α) + r(α) ≡ r(α) mod p. so α must be a solution to r(x) ≡ 0 mod p. Since f(x) has distinct roots, …
Webmod p2, even though it has a root mod p. More to the point, if one wants a fast deterministic algorithm, one can not assume that one has access to individual roots. This is because it is still an open problem to find the roots of univariate polynomials modulo p in deterministic polynomial time (see, e.g., [11, 16]). WebHensel's lemma is a result that stipulates conditions for roots of polynomials modulo powers of primes to be "lifted" to roots modulo higher powers. The lifting method outlined in the proof is reminiscent of Newton's method for solving equations. The lemma is useful for finding and classifying solutions of polynomial equations modulo …
WebHowever, there exist polynomials that have roots modulo every positive inte-ger but do not have any rational root. Such polynomials provide counterexamples to the local-global principle in number theory ... So the result follows by applying Theorem 1 …
