Jcp. Bueno, ON THE BICROSSPRODUCT STRUCTURES FOR THE U-LAMBDA(ISO(OMEGA-2, ... OMEGA-N)(N)) FAMILY OF ALGEBRAS, Journal of physics. A, mathematical and general, 31(30), 1998, pp. 6505-6516
It is shown that the family of deformed algebras U-lambda(iso omega(2)
,...,omega(N), (N)) has a different bicrossproduct structure for each
omega(a) = 0 in analogy to the undeformed case.
