On projective-symmetric spaces [PDF]

open access: bronzeJournal of the Australian Mathematical Society, 1964
This paper deals with a type of Remannian space Vn (n ≧ 2) for which the first covariant dervative of Weyl's projective curvature tensor is everywhere zero, that is where comma denotes covariant differentiation with respect to the metric tensor gij of Vn. Such a space has been called a projective-symmetric space by Gy. Soós [1].

The space of twisted cubics [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2021
We consider the Cohen-Macaulay compactification of the space of twisted cubics in projective n-space. This compactification is the fine moduli scheme representing the functor of CM-curves with Hilbert polynomial 3t+1. We show that the moduli scheme of CM-

Fractal Dimension of Fractal Functions on the Real Projective Plane

open access: yesFractal and Fractional, 2023
In this article, we consider an iterated functions system on the non-Euclidean real projective plane which has a linear structure. Then, we study the fractal dimension of the associated curve as a subset of the projective space and like a set of the ...

Projective bundles and blowing ups

open access: yesComptes Rendus. Mathématique, 2021
We study the blowing up $\widetilde{X}$ of a smooth projective variety $X$ along a smooth center $B$ that is equipped with a projective bundle structure over a variety $Z$. If $B$ is a point, then $X$ is a projective space. If the Picard number $\rho (X)$

On Projective 3-Space [PDF]

open access: yesEngineering and Technology Journal, 2009
The purpose of this work is to give some definitions and prove some theorems onprojective 3-space S=PG(3,K) over a field K.Also, the principle of duality in S is given which state that any theorem true in theprojective 3-space concerned with the points ...

On the quaternion projective space

open access: yesJournal of Taibah University for Science, 2020
Apart from being a vital and exciting field in mathematics with interesting results, projective spaces have various applications in design theory, coding theory, physics, combinatorics, number theory and extremal combinatorial problems. In this paper, we

Neutrosophic projective G-submodules [PDF]

open access: yesNeutrosophic Sets and Systems, 2020
A significant area of module theory is the concept of free modules, projective modules and injective modules. The goal of this study is to characterize the projective G-modules under a single-valued neutrosophic set.

On the properties of the projective Lie algebras of rigid h-spaces H32 of the type {32}

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2020
The five-dimensional pseudo-Riemannian spaces that admit infinitesimal projective transformations were studied. A general solution of the Eisenhart equation in the h-space H32 of non-constant curvature was found.
