Algebraic structure of the Lorentz and of the Poincaré Lie algebras

Pablo Alberca Bjerregaard, Dolores MartÍn Barquero, CÁndido MartÍn GonzÁlez +1

We start with the Lorentz algebra $L=o_R(1,3)$ over the reals and find a suitable basis $B$ relative to which the structure constants are integers. Thus we consider the $Z$-alge…
