On Quantum Deformations of D=4 Conformal Algebra
A. Frydryszak, J. Lukierski, P. Minnaert +1
Three classes of classical r-matrices for sl(4,C) algebra are constructed in quasi-Frobenius algebra approach. They satisfy CYBE and are spanned respectively on 8,10,12 generators.…

Quantum Deformations of Conformal Algebras Introducing Fundamental Mass Parameters
Jerzy Lukierski, Pierre Minnaert, Marek Mozrzymas
We consider new class of classical r-matrices for D=3 and D=4 conformal Lie algebras. These r-matrices do satisfy the classical Yang-Baxter equation and as two-tensors belong to th…

Racah Sum Rule and Biedenharn-Elliott Identity for the Super-Rotation symbols
Pierre Minnaert, Stoyan Toshev
It is shown that the well known Racah sum rule and Biedenharn-Elliott identity satisfied by the recoupling coefficients or by the symbols of the usual rotation algebr…
