Twisted partially pure spinors
Rafael Herrera, Ivan Tellez
Motivated by the relationship between orthogonal complex structures and spure spinors, we define twisted partially pure spinors in order to characterize spinorially subspaces of Eu…
Almost even-Clifford hermitian manifolds with large automorphism group
Gerardo Arizmendi, Rafael Herrera, Noemi Santana
We study manifolds endowed with an (almost) even Clifford (hermitian) structure and admitting a large automorphism group. We classify them when they are simply connected and the di…
Spinorially Twisted Spin Structures. II: Twisted Pure Spinors, Special Riemannian Holonomy and Clifford Monopoles
Rafael Herrera, Noemi Santana
We introduce a notion of twisted pure spinor in order to characterize, in a unified way, all the special Riemannian holonomy groups just as a classical pure spinor characterizes th…
Metrics of constant scalar curvature on sphere bundles
Nobuhiko Otoba, Jimmy Petean
Let be a Riemannian homogeneous space. For an orthogonal representation of on the Euclidean space , there corresponds the vector bundle $E=G\times_ϕ…
The dancing metric, -symmetry and projective rolling
Gil Bor, Luis Hernández Lamoneda, Pawel Nurowski
The "dancing metric" is a pseudo-riemannian metric of signature on the space of non-incident point-line pairs in the real projective plane .…
Non-strongly isospectral spherical space forms
Emilio A. Lauret, Roberto J. Miatello, Juan Pablo Rossetti
In this paper we describe recent results on explicit construction of lens spaces that are not strongly isospectral, yet they are isospectral on -forms for every . Such exampl…
