Traditional Houses and Projective Geometry: Building Numbers and Projective Coordinates
Journal of Applied Mathematics, 2021 The natural mathematical abilities of humans have advanced civilizations. These abilities have been demonstrated in cultural heritage, especially traditional houses, which display evidence of an intuitive mathematics ability. Tribes around the world have

Projective geometry of Sasaki–Einstein structures and their compactification [PDF]
Dissertationes Mathematicae, 2018 We show that the standard definitions of Sasaki structures have elegant and simplifying interpretations in terms of projective differential geometry. For Sasaki-Einstein structures we use projective geometry to provide a resolution of such structures ...

Gorenstein-Projective Modules over Upper Triangular Matrix Artin Algebras
Journal of Mathematics, 2021 Gorenstein-projective module is an important research topic in relative homological algebra, representation theory of algebras, triangulated categories, and algebraic geometry (especially in singularity theory).

Convex cocompact actions in real projective geometry [PDF]
Annales Scientifiques de l'Ecole Normale Supérieure, 2017 We study a notion of convex cocompactness for (not necessarily irreducible) discrete subgroups of the projective general linear group acting on real projective space, and give various characterizations.

International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary In this contribution, we propose a detailed study of interpolation‐based data‐driven methods that are of relevance in the model reduction and also in the systems and control communities. The data are given by samples of the transfer function of the underlying (unknown) model, that is, we analyze frequency‐response data.

Graph decompositions in projective geometries [PDF]
Journal of Combinatorial Designs, 2020 AbstractLet PG be the ‐dimensional projective space over and let be a simple graph of order for some . A design over is a collection of graphs (blocks) isomorphic to with the following properties: the vertex set of every block is a subspace of PG; every two distinct points of PG are adjacent in exactly blocks.

Einstein on involutions in projective geometry [PDF]
Archive for History of Exact Sciences, 2021 AbstractWe discuss Einstein’s knowledge of projective geometry. We show that two pages of Einstein’s Scratch Notebook from around 1912 with geometrical sketches can directly be associated with similar sketches in manuscript pages dating from his Princeton years.

Geometry of straight lines pencils [PDF]
Facta Universitatis. Series: Architecture and Civil Engineering, 2002 This paper considers a pencil of straight Unes in the Euclidean plane as well as the same pencil of straight lines in the projective plane where the projective geometry model M" is defined with its points forming the sets of (n-l) collinear points, whose

Proyeksi Geometri Fuzzy pada Ruang
Cauchy: Jurnal Matematika Murni dan Aplikasi, 2012 Fuzzy geometry is an outgrowth of crisp geometry, which in crisp geometry elements are exist and not exist, but also while on fuzzy geometry elements are developed by thickness which is owned by each of these elements.
