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…
Centralizers of spin subalgebras
Gerardo Arizmendi, Rafael Herrera
We determine the centralizers of certain isomorphic copies of spin subalgebras in , where is the dimension of a real irreducible rep…
