Maps to Spaces in the Genus of Infinite Quaternionic Projective Space [PDF]

open access: green, 2003
Spaces in the genus of infinite quaternionic projective space which admit essential maps from infinite complex projective space are classified. In these cases the sets of homotopy classes of maps are described explicitly. These results strengthen the classical theorem of McGibbon and Rector on maximal torus admissibility for spaces in the genus of ...

Ambient surgery and tangential homotopy quaternionic projective spaces. [PDF]

open access: bronzeTransactions of the American Mathematical Society, 1969
Introduction. In this paper the word manifold will always mean oriented compact C "-manifold. Unless otherwise specified, all homology and cohomology is taken with integral coefficients, and for Mn an n-manifold, [M] E Hn(M, AM) will denote the orientation class of M. A mapf: M-N between n-manifolds is of degree +1 iff*([M])=[N].

On Connectedness of the Space of Harmonic 2-Spheres in Quaternionic Projective Spaces [PDF]

open access: hybridTokyo Journal of Mathematics, 1994
Let \(\mathbb{H} P^ n(c)\) be an \(n\)-dimensional quaternionic projective space with the maximum \(c\) of the sectional curvatures. It is known that there are two natural twistor spaces \({\mathcal T}_ n\) and \(\mathbb{C} P^{2n +1}\) over \(\mathbb{H} P^ n\). A harmonic map \(\varphi : \Sigma \to\mathbb{H} P^ n(c)\) is called strongly isotropic (resp.

A characterization of geodesic hyperspheres of quaternionic projective space [PDF]

open access: bronzeTsukuba Journal of Mathematics, 1997
Let \(M\) be a real hypersurface of a quaternionic projective space \(QP^m\), \(m\geq 3\). Denote by \(R\) the Riemannian curvature tensor and by \(A\) the shape operator of \(M\). The author proves that \(M\) is an open part of a geodesic hypersphere in \(QP^m\) if and only if \(R(X,Y) AZ+R(Y,Z) AX+R(Z,X) AY=0\) holds for all vector fields \(X,Y,Z ...

A NOTE ON THE QUATERNIONIC QUASI-PROJECTIVE SPACE

open access: bronzeMemoirs of the Faculty of Science, Kyushu University. Series A, Mathematics, 1984
According to \textit{I. M. James} [The topology of Stiefel manifolds, Lond. Math. Soc. Lect. Note Ser. 24 (1976; Zbl 0337.55017)], the quaternionic quasi-projective space \({\mathbb{H}}{\mathbb{Q}}_ n\) is defined in two ways. In this paper the authors show that the two definitions are equivalent and that the map \(t_ n: {\mathbb{H}}{\mathbb{Q}}_ n\to ...

On submersion and immersion submanifolds of a quaternionic projective space [PDF]

open access: diamondActa Universitatis Sapientiae, Mathematica, 2016
Abstract We study submanifolds of a quaternionic projective space, it is of great interest how to pull down some formulae deduced for submanifolds of a sphere to those for submanifolds of a quaternionic projective space.
