The Smith normal form of Laplacian matrices of simplicial annuli and high dimensional trees
Carlos A. Alfaro, Jesús Uriel Medrano, Juan Pablo Serrano +2
Inspired by the generalization of the formula of determinant of the distance matrix of trees to -trees, we study the Smith normal form of Laplacian matrices associated with some…
Twistor sections of Dirac bundles
Sergio A. H. Cardona, Pedro Solórzano, Iván Téllez
A Dirac bundle is a euclidean bundle over a riemannian manifold which is a compatible left -module, together with a metric connection also compatible with the Cliffor…
Spinorially twisted Spin structures, III: CR structures
Rafael Herrera, Roger Nakad, Ivan Tellez
We develop a spinorial description of CR structures of arbitrary codimension. More precisely, we characterize almost CR structures of arbitrary codimension on (Riemannian) manifold…
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…
