Images of the Scenic Space between Reality and Illusion. Projective Transformations of the Scene in the Renaissance Theatre

open access: yesProceedings, 2017
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.

Projective dimension in filtrated K-theory [PDF]

open access: yes, 2013
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.

On the level of projective spaces

open access: yesCommentarii Mathematici Helvetici, 1987
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

A space of projections on the Bergman space [PDF]

open access: yesAnnales Academiae Scientiarum Fennicae Mathematica, 2010
We define a set of projections on the Bergman space A 2 , which is parameterized by an ane subset of a Banach space of holomorphic functions in the disk and which includes the classical Forelli-Rudin projections.

Applications of a Particular Four-Dimensional Projective Geometry to Galactic Dynamics

open access: yesGalaxies, 2018
Relativistic location systems that extend relativistic positioning systems show that pseudo-Riemannian space-time geometry is somehow encompassed in a particular four-dimensional projective geometry.

Centered planes in the projective connection space

open access: yesДифференциальная геометрия многообразий фигур, 2020
The space of centered planes is considered in the Cartan projec­ti­ve connection space . The space is important because it has con­nec­tion with the Grassmann manifold, which plays an important role in geometry and topology, since it is the basic space ...

On projective coordinate spaces

open access: yesFilomat, 2015
In the present study, an (n+1)-dimensional module over the local ringK = Mmm(R) is constructed. Further, an n-dimensional projective coordinate space over this module is constructed with the help of equivalence classes. The points and lines of this space are determined and the points are classified.

Fibers of rational maps and Rees algebras of their base ideals

open access: yesTạp chí Khoa học Đại học Huế: Khoa học Tự nhiên, 2020
We consider a ratinonal map $\phi$ from m-dimensional projective space to n-dimensional projective space that is a parameterization of m-dimensional variety. Our main goal is to study the (m-1)-dimensional fibers of $\phi$ in relation with the m-th local
