A factorization formula for power seriesArticle
Authors: Daniel Birmajer 1; Juan B. Gil 2; Michael D. Weiner 2
Given an odd prime p, we 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 $p^w$ with $w>1$. Our formulas are given in terms of partial Bell polynomials and rely on the inversion formula of Lagrange.
