An extension of Mobius--Lie geometry with conformal ensembles of cycles and its implementation in a GiNaC library

Pracì Mìžnarodnogo Geometričnogo Centru, 2018
We propose to consider ensembles of cycles (quadrics), which are interconnected through conformal-invariant geometric relations (e.g. ``to be orthogonal'', ``to be tangent'', etc.), as new objects in an extended M\"obius--Lie geometry.

Etale cohomologies of quadrics over R

, 2022
In this paper, we study etale cohomologies of quadrics over R. An element in the etale cohomology is called algebraic, if it is in the image of the cycle map from the Chow ring.

Radial Kernels Collocation Method for the Solution of Volterra Integro-Differential Equations

Science, Engineering and Technology
Radial kernel interpolation is an advanced method in approximation theory for the construction of higher order accurate interpolants for scattered data up to higher dimensional spaces. In this manuscript, we formulate a radial kernel collocation approach

On the number of quadrics in Rn

, 2002
In this note we give a short proof of the fact that the number of equivalent quadrics in Rn relative to affine transformations is n 2 + 3n − 1. The well known result for the number of equivalent quadrics relative to projective transformations is also ...

Motivic cohomology of quadrics and the coniveau spectral sequence

, 2010
We study the coniveau spectral sequence for quadrics defined by Pfister forms. In particular, we explicitly compute the motivic cohomology of anisotropic quadrics over ℝ, by showing that their coniveau spectral sequences collapse from the ...

On the intersection of three quadrics.

Journal für die reine und angewandte Mathematik (Crelles Journal), 1989
Let \(\{X_ t\}_{t\in {\mathbb{P}}^ 1}\) be a generic Lefschetz pencil where \(X_ t\) is the base locus of a net of \((2k+3)\)-dimensional quadrics in \({\mathbb{P}}^{2k+4}\) and \(X_ t\) is non singular for \(t\in {\mathbb{P}}^ 1-\{t_ 1,...,t_ n\}\). In this note the Fano varieties \(S_ t\) parametrizing the k-dimensional quadrics contained in \(X_ t\)

On pencil of quadrics in I3(2) [PDF]

, 2005
An affine space A3 is called a double isotropic space I3 (2) , if in A3 a metric is induced by an absolute , f , F, consisting of the line f in the plane of infinity of A3, and a point F in f .
