Nontriviality of the module of relations for degree 4 polynomials

  • Á Serrano Holgado

摘要

We characterize the nontriviality of the module of relations of an irreducible quartic polynomial in terms of a quotient between its roots. In the case where the base field is \(\mathbb{Q}\) Q , we also give a characterization in terms of the roots of the cubic resolvent of the polynomial.
