Fast and Robust QEF Minimization using Probabilistic Quadrics
Computer graphics forum (Print), 2020 Error quadrics are a fundamental and powerful building block in many geometry processing algorithms. However, finding the minimizer of a given quadric is in many cases not robust and requires a singular value decomposition or some ad‐hoc regularization ...

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2023 We use Bott's residue formula to infer that a general cubic surface in the projective space P^3_C contains exactly twenty seven lines and that a general complete intersection of two quadrics in P^4_C contains exactly sixteen lines.

All minimal [9,4] 2 -codes are hyperbolic quadrics
Examples and Counterexamples, 2023 Minimal codes are being intensively studied in last years. [n,k]q-minimal linear codes are in bijection with strong blocking sets of size n in PG(k−1,q)and a lower bound for the size of strong blocking sets is given by (k−1)(q+1)≤n.

Graphic representation of a triaxial ellipsoid by means of a sphere in general collinear spaces [PDF]
Facta Universitatis. Series: Architecture and Civil Engineering, 2011 For graphic representation of the projective creations, such as the quadrics (II degree surfaces) in projective, general collinear spaces, it is necessary to firstly determine the characteristic parameters, such as: vanishing planes, axes and centers ...

Singular spin structures and superstrings
Journal of High Energy Physics, 2023 There are two main problems in finding the higher genus superstring measure. The first one is that for g ≥ 5 the super moduli space is not projected. Furthermore, the supermeasure is regular for g ≤ 11, a bound related to the source of singularities due ...

Michigan Mathematical Journal, 2020 Quadric complexes are square complexes satisfying a certain combinatorial nonpositive curvature condition. These complexes generalize 2-dimensional CAT(0) cube complexes and are a square analog of systolic complexes. We introduce and study the basic properties of these complexes.

Cyclic surfaces accompanying non-ruled quadrics of rotation
Омский научный вестник, 2023 The paper considers the shaping of cyclic surfaces based on nonlinear rotation, in which the axis of rotation and the generatrix in the general case are three-dimensional smooth curves. As a tool for shaping surfaces of non-linear rotation, the method of

On the birational geometry of spaces of complete forms I: collineations and quadrics [PDF]
Proceedings of the London Mathematical Society, 2018 Moduli spaces of complete collineations are wonderful compactifications of spaces of linear maps of maximal rank between two fixed vector spaces. We investigate the birational geometry of moduli spaces of complete collineations and quadrics from the ...

On a Discretization of Confocal Quadrics. A Geometric Approach to General Parametrizations [PDF]
International mathematics research notices, 2017 We propose a discretization of classical confocal coordinates. It is based on a novel characterization thereof as factorizable orthogonal coordinate systems.
