Let En d be the set of n-tuples (p1,..., pn) of mutually coprime monic polynomials of degree d. Equivalently (in terms of the roots of the polynomials) En d is the set of n-tuples (ξ1,..., ξn) of positive divisors in C of degree d, such that ξi∩ ξj=∅ whenever i= j. A positive divisor ξ in C of degree d is simply an element∑ d i= 1 αi of the symmetric product Spd (C)∼= Cd, so the set En d acquires a natural topology as an open subspace of the n-fold product of Sd (C). It is therefore a complex manifold of dimension dn.
