The implicit equation of a multigraded hypersurface
(Elsevier Inc, 2011-12)
In this article we analyze the implicitization problem of the image of a rational map φ : X Pn, with X a toric variety of dimension n − 1 defined by its Cox ring R. Let I := (f0,..., fn) be n + 1 homogeneous elements of ...
Compactifications of rational maps, and the implicit equations of their images
(Elsevier Science, 2010-05)
In this paper, we give different compactifications for the domain and the codomain of an affine rational map f which parameterizes a hypersurface. We show that the closure of the image of this map (with possibly some other ...
A relation between number of integral points, volumes of faces and degree of the discriminant of smooth lattice polytopesUne relation entre nombre de points entiers, volumes des faces et degré du discriminant des polytopes entiers non singuliers
(Elsevier Masson, 2012-03)
We present a formula for the degree of the discriminant of a smooth projective toric variety associated to a lattice polytope P, in terms of the number of integral points in the interior of dilates of faces of dimension ...
