Null-plane Quantum Poincaré Algebras and their Universal $R$-matrices

A. Ballesteros, F. J. Herranz, M. A. del Olmo +1

A non-standard quantum deformation of the Poincaré algebra is presented in a null-plane framework for 1+1, 2+1 and 3+1 dimensions. Their corresponding universal $R$-matrices are ob…
