On Hensel's roots and a factorization formula in Z[[x]]
arXiv:1308.2987
Abstract
Given an odd prime , we provide formulas for the Hensel lifts of polynomial roots modulo , and give an explicit factorization over the ring of formal power series with integer coefficients for certain reducible polynomials whose constant term is of the form with . All of our formulas are given in terms of partial Bell polynomials and rely on the inversion formula of Lagrange.
