Designs related through projective and Hopf maps [PDF]

open access: yes, 2023
We formalize constructions which use the $\Bbb F$-projective map to build a spherical $t$-design on $S^d$ from a projective $\left\lfloor\frac t2\right\rfloor$-design on a real, complex, quaternionic, or octonionic projective space $\Bbb{FP}^n\neq \Bbb ...

The maximal codegree of the quaternionic projective spaces

open access: yesHiroshima Mathematical Journal, 1990
Let \(\alpha\) be a k-dimensional orientable real vector bundle over a finite connected CW-complex X with Thom space \(X^{\alpha}\) and i: \(S^ k=\{x_ 0\}^{\alpha}\to X^{\alpha}\) the canonical inclusion. For a multiplicative cohomology theory \(E^*\) with unit 1 define the E- codegree of \(\alpha\), \(cd^ E(\alpha)\) to be the smallest \(n\in {\mathbb{

Rigidity in Complex Projective Space. [PDF]

open access: yes
An open convex set in real projective space is called divisible if there exists a discrete group of projective automorphisms which acts co-compactly. There are many examples of such sets and a theorem of Benoist implies that many of these examples are ...

Stable unextendibility of vector bundles over the quaternionic projective spaces [PDF]

open access: yes, 2003
We study the stable unextendibility of vector bundles over the quaternionic projective space HP^n by making use of combinatorial properties of the Stiefel-Whitney classes and the Pontrjagin classes.

Characteristic classes of vector bundles over RP(h)×HP(k) [PDF]

open access: yes, 2007
This paper determines the total Stiefel–Whitney classes of vector bundles over the product of the real projective space RP(h) with the quaternionic projective space HP(k).
