Representable functor

In the article, we see that the birational maps of degree d of the projective space Pn k form a locally closed subvariety of the projective space P(Sdn11), denoted Crd(n). In this paper, we will construct the notion of extended degree of rational maps, then we obtain the functor crd(n) that represents the variety Crd(n).
