F. Thuillier et Jc. Wallet, TWISTED Q-COVARIANT OSCILLATOR ALGEBRAS FOR U(Q)(OSP(1,2)) AND U(Q)(OSP(2,2)), Physics letters. Section B, 323(2), 1994, pp. 153-160
We construct q-covariant oscillator algebras for U(q)(osp(1, 2)) and U
(q)(osp(2, 2)), using an R-matrix formalism. We show in each case that
the twisted oscillator algebra, invariant under natural q-transformat
ions of the oscillators induced by the coproduct, can be compactly exp
ressed with the help of the intertwining matrix.
