Peterson's Deformations of Higher Dimensional Quadrics [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2010 We provide the first explicit examples of deformations of higher dimensional quadrics: a straightforward generalization of Peterson's explicit 1-dimensional family of deformations in C^3 of 2-dimensional general quadrics with common conjugate system ...

Tangent quadrics in real 3-space [PDF]
, 2021 We examine quadratic surfaces in 3-space that are tangent to nine given figures. These figures can be points, lines, planes or quadrics. The numbers of tangent quadrics were determined by Hermann Schubert in 1879.

Canadian Journal of Mathematics, 2019 AbstractAn intrinsic quadric is a normal projective variety with a Cox ring defined by a single quadratic relation. We provide explicit descriptions of these varieties in the smooth case for small Picard numbers. As applications, we figure out in this setting the Fano examples and (affirmatively) test Fujita’s freeness conjecture.

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.

A comparison of Landau-Ginzburg models for odd-dimensional Quadrics [PDF]
, 2018 In [Rie08], the second author defined a Landau-Ginzburg model for homogeneous spaces G/P, as a regular function on an affine subvariety of the Langlands dual group.

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 ...

Quadrics and Scherk towers. [PDF]
Mon Hefte Math, 2018 We investigate the relation between quadrics and their Christoffel duals on the one hand, and certain zero mean curvature surfaces and their Gauss maps on the other hand. To study the relation between timelike minimal surfaces and the Christoffel duals of 1-sheeted hyperboloids we introduce para-holomorphic elliptic functions. The curves of type change
