An inequality about factors of polynomials

M. Mignotte
1974 Mathematics of Computation  
A sharp inequality is proved about the product of some roots of a polynomial. It is used to bound the height of the factors of a polynomial. Applications are given to the problem of factorization and numerical examples show that these bounds strongly improve the previous ones.
