Chow transformation of coherent sheaves
Complex Manifolds, 2023 We define a dual of the Chow transformation of currents on any complex projective manifold. This integral transformation is a factor of a left inverse of the Chow transformation and its composition with the Chow transformation is a right inverse of a ...

ON PROJECTIONS IN PROJECTIVE SPACES
Demonstratio Mathematica, 1998 Die Verff. betonen, daß eine projektive Kollineation \(\varphi\) eines projektiven Raumes \(PG(V)\), \(V\) ein Vektorraum der Dimension \(\geq 2\), auch dadurch definiert werden kann, daß \(\varphi|_U\) für einen wenigstens 2-dimensionalen linearen Unterraum \(U\) eine solche ist.

Ropes in projective space [PDF]
Kyoto Journal of Mathematics, 1996 Let \(C\) be a smooth irreducible curve in \(\mathbb{P}^n\) with homogeneous ideal \(I\). A locally Cohen-Macaulay structure \(Y\) of multiplicity \(\alpha\) on \(C\) is said to be an \(\alpha\)-rope on \(C\), if its homogeneous ideal \(J\) satisfies \(I^2 \subset J\subset I\). A ribbon is a 2-rope.

Projective embedding of projective spaces [PDF]
Bulletin of the Belgian Mathematical Society - Simon Stevin, 1998 The author studies embeddings \(\phi:M \rightarrow P\) from a linear space \(M\) in a linear space \(P\). Examples of embeddings with \(\dim M >\dim P\) are given, but the author also focusses on conditions on embeddings such that \(\dim M=\dim P\). He introduces two properties (\textbf{G}) and (\textbf{E}) and he also describes a condition called the \

Curvature tensor of connection in principal bundle of Cartan's projective connection space
Дифференциальная геометрия многообразий фигур, 2019 We considered Cartan's projective connection space with structure equations generalizing the structure equations of the projective space and the condition of local projectivity (this condition is an analogue to the equiprojectivity condition in the ...

Brillouin Klein bottle from artificial gauge fields
Nature Communications, 2022 Topological states are exploited based on crystalline symmetry, but under artificial gauge fields, symmetries may satisfy projective algebras, which remains less studied.

Cofinitely and co-countably projective spaces
Applied General Topology, 2002 We show that X is cofinitely projective if and only if it is a finite union of Alexandroff compactatifications of discrete spaces. We also prove that X is co-countably projective if and only if X admits no disjoint infinite family of uncountable cozero ...

Extensions of maps to the projective plane [PDF]
, 2005 It is proved that for a 3-dimensional compact metrizable space X the infinite real projective space is an absolute extensor of X if and only if the real projective plane is an absolute extensor of X.Comment: Published by Algebraic and Geometric Topology ...

Categories of projective spaces
Journal of Pure and Applied Algebra, 1996 Starting with an abelian category \({\mathcal A}\), a natural construction [the second author, ``Transfer functors and projective spaces'', Math. Nachr. 118, 147-165 (1984; Zbl 0556.18005)] produces a category \(\mathbb{P} {\mathcal A}\) such that if \({\mathcal A}\) is a category of vector spaces, then \(\mathbb{P} {\mathcal A}\) is the corresponding ...
