Bounds for the zeros of complex-coefficient polynomials

In this paper, we present certain results on the bounds for the moduli of the zeros of a polynomial with complex coefficients which among other things contain some generalizations and refinements of classical results due to Cauchy, Tôya, Carmichael and Mason, Williams and others. Nous obtenons quelques raffinements de résultats dûs à Cauchy, Tôya, Carmichael, Mason, Williams et d’autres concernant la location des zéros de polynômes algébriques.
