An arc is a set of points of the \((k-1)\)-dimensional projective space over the finite field with q elements \({\mathbb F}_q\), in which every k-subset spans the space. In this article, we firstly review Glynn’s construction of large arcs which are contained in the intersection of quadrics. Then, for q odd, we construct a series of matrices \(\mathrm {

Controlling Quadric Error Simplification with Line Quadrics
Computer Graphics ForumAbstractThis work presents a method to control the output of mesh simplification algorithms based on iterative edge collapses. Traditional mesh simplification focuses on preserving the visual appearance. Despite still being an important criterion, other geometric properties also play critical roles in different applications, such as triangle quality ...

Abstract IN the projective plane the simplest locus that we can consider, apart from the straight line, is the conic locus, and we have already seen how to establish its projective properties. In three-dimensional projective space, on the other hand, where a point has three degrees of freedom, there are two essentially different kinds of

ON AN INVARIANT OF A BUNDLE OF QUADRICS
Mathematics of the USSR-Izvestiya, 1975It is shown how the Hesse curve and theta-characteristic of a bundle of quadrics can be used to reconstruct the initial bundle. The corresponding construction is used to prove the global Torelli theorem for the intersection of three quadrics.Bibliography: 2 ...

Computer Aided Geometric Design, 1993
The author presents practical examples of quadratic Bézier patches on the sphere. [A theoretical underpinning of the entire problem has been given by \textit{R. Dietz, J. Hoschek} and \textit{B. Jüttler}, ibid. 10, No. 3-4, 211-229 (1993; Zbl 0781.65009)].

Let \(L\) be a linear form on the Galois field \(GF(q^{n + 1})\) over \(GF(q)\) \((n \geq 2)\). The authors characterize those integers \(s\) coprime to \(v = (q^{n + 1} - 1)/(q - 1)\) such that \(L(x^s)\) is (or is related to) a quadratic form on \(GF(q^{n + 1})\) over \(GF(q)\). This relates to a conjecture of Games (see \textit{R. A.
