Revisiting Clifford algebras and spinors II: Weyl spinors in Cl(3,0) and Cl(0,3) and the Dirac equation
Roldao da Rocha, Jayme Vaz
This paper is the second one of a series of three and it is the continuation of math-ph/0412074. We review some properties of the algebraic spinors in Cl(3,0) and Cl(0,3) and how W…

Twistors, Generalizations and Exceptional Structures
Roldao da Rocha, Jayme Vaz
This paper is intended to describe twistors via the paravector model of Clifford algebras and to relate such description to conformal maps in the Clifford algebra over R(4,1), besi…

AdS Geometry, projective embedded coordinates and associated isometry groups
Roldao da Rocha, E. Capelas de Oliveira
This work is intended to investigate the geometry of anti-de Sitter spacetime (AdS), from the point of view of the Laplacian Comparison Theorem (LCT), and to give another descripti…
