Some examples of vector fields on the 3-sphere

F. Wesley Wilson (1970)

Annales de l'institut Fourier

Let $S^{3}$ denote the set of points with modulus one in euclidean 4-space $R^{4}$ ; and let $Γ_{0}^{1} (S^{3})$ denote the space of nonsingular vector fields on $S^{3}$ with the $C^{1}$ topology. Under what conditions are two elements from $Γ_{0}^{1} (S^{3})$ homotopic ? There are several examples of nonsingular vector fields on $S^{3}$ . However, they are all homotopic to the tangent fields of the fibrations of $S^{3}$ due to H. Hopf (there are two such classes).We construct some new examples of vector fields which can be classified geometrically. Each of these examples...

Some remarks on Koszul algebras and quantum groups

Yu. I. Manin (1987)

Annales de l'institut Fourier

The category of quadratic algebras is endowed with a tensor structure. This allows us to construct a class of Hopf algebras studied recently under the name of quantum (semi) groups.

Some results on the real K-theory of certain homogeneus spaces.

Michael Olusanya Ajetunmobi (1988)

Publicacions Matemàtiques

Let Fr(n) be the incomplete complex flag manifold of length r in Cn. We make a start on the complete determination of the torsion part of the group KO-i(Fr(n)) giving results here when r = 2, 3.

Spaces and equations

Walter Taylor (2000)

Fundamenta Mathematicae

It is proved, for various spaces A, such as a surface of genus 2, a figure-eight, or a sphere of dimension ≠ 1,3,7, and for any set Σ of equations, that Σ cannot be modeled by continuous operations on A unless Σ is undemanding (a form of triviality that is defined in the paper).
