Chow transformation of coherent sheaves
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 ...

Topology and geometry of the canonical action of $T^4$ on the complex Grassmannian $G_{4,2}$ and the complex projective space $CP^{5}$ [PDF]
We consider the canonical action of the compact torus $T^4$ on the Grassmann manifold $G_{4,2}$ and prove that the orbit space $G_{4,2}/T^4$ is homeomorphic to the sphere $S^5$.

Categories of projective spaces
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 ...

Extensions of maps to the projective plane [PDF]
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 ...

On the level of projective spaces
By definition [see \textit{Z. D. Dai} and \textit{T. Y. Lam}, ibid. 59, 376--424 (1984; Zbl 0546.10017)] the level of a topological space \(X\) with a fixed point free involution \(i\) is the number \(s(X,i)=\min \{n:\) there is a \(\mathbb Z/2\)-equivariant map \(f: X\to S^{n-1}\}\). Here \(S^{n-1}\) has a \(\mathbb Z/2\)-action given by the antipodal

This study focuses on an analysis of perceiving the infinite “solid images” derived from the projective transformations of space in a relief perspective, with particular reference to Renaissance theatre scenery.

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

Projective dimension in filtrated K-theory [PDF]
Under mild assumptions, we characterise modules with projective resolutions of length n in the target category of filtrated K-theory over a finite topological space in terms of two conditions involving certain Tor-groups.

Hyperbolicity of generic high-degree hypersurfaces in complex projective space [PDF]
We use two ingredients to prove the hyperbolicity of generic hypersurfaces of sufficiently high degree and of their complements in the complex projective space.
