WebMar 24, 2024 · A modular inverse of an integer b (modulo m) is the integer b^(-1) such that bb^(-1)=1 (mod m). A modular inverse can be computed in the Wolfram Language using PowerMod[b, -1, m]. Every nonzero integer b has an inverse (modulo p) for p a prime and b not a multiple of p. For example, the modular inverses of 1, 2, 3, and 4 (mod 5) are 1, 3, 2, …
WebIn mathematics, Hensel's lemma, also known as Hensel's lifting lemma, named after Kurt Hensel, is a result in modular arithmetic, stating that if a univariate polynomial has a simple root modulo a prime number p, then this root can be lifted to a unique root modulo any higher power of p.More generally, if a polynomial factors modulo p into two coprime … primal winterWebSolves a system of linear equations given as PolyElement instances of a PolynomialRing.
