This article will begin with the claim that Hamilton spent a great deal of time trying to figure out the three-dimensional complex numbers. He was never able to accomplish that.

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 geometry for blueprints [PDF]
In this note, we generalize the Proj-construction from usual schemes to blue schemes. This yields the definition of projective space and projective varieties over a blueprint.

Curvature tensor of connection in principal bundle of Cartan's projective connection space
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 ...

ON PROJECTIONS IN PROJECTIVE SPACES
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.

Cofinitely and co-countably projective spaces
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 ...

ADHM construction of perverse instanton sheaves [PDF]
We present a construction of framed torsion free instanton sheaves on a projective variety containing a fixed line which further generalizes the one on projective spaces. This is done by generalizing the so called ADHM variety.

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.

Centered planes in the projective connection space
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 ...

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