For a smooth projective n-dimensional variety X⊂PN, let W be a linear subspace of PN of dimension N-n-1 that is disjoint from X and let πW:X→PN be the linear projection associated to W. A natural question to ask is: when does this projection induce a Galois extension of function fields? We will address this question in the case that X is an abelian variety. Moreover, we will relate this discussion to a question asked by Ekedahl and Serre on Jacobian varieties that are isogenous to the product of elliptic curves.
