Multiplicative excellent families of elliptic surfaces of type E[subscript 7] or E[subscript 8]

We describe explicit multiplicative excellent families of rational elliptic surfaces with Galois group isomorphic to the Weyl group of the root lattices E[subscript 7] or E[subscript 8]. The Weierstrass coefficients of each family are related by an invertible polynomial transformation to the generat...

description We describe explicit multiplicative excellent families of rational elliptic surfaces with Galois group isomorphic to the Weyl group of the root lattices E[subscript 7] or E[subscript 8]. The Weierstrass coefficients of each family are related by an invertible polynomial transformation to the generators of the multiplicative invariant ring of the associated Weyl group, given by the fundamental characters of the corresponding Lie group. As an application, we give examples of elliptic surfaces with multiplicative reduction and all sections defined over Q for most of the entries of fiber configurations and Mordell–Weil lattices described by Oguiso and Shioda, as well as examples of explicit polynomials with Galois group W(E[subscript 7]) or W(E[subscript 8]).
