چکیده
The structure of r-fold tensor products of irreducible tame representations of U(∞) = lim −→U(n) are described, versions of contragredient representations and invariants are realized, and methods of calculating multiplicities, Clebsch-Gordan and Racah coefficients are given using invariant theory on Bargmann-Segal-Fock spaces. PACS codes: 02.20.Tw, 02.20.QS, 03.65.Fd

Hilbert space representations of the cross product ∗-algebras of the Hopf ∗-algebra Uq(su2) and its module ∗-algebras O(Sqr) of Podles’ spheres are investigated and classified by describing the action of generators. The representations are analyzed within two approaches. It is shown that the Hopf ∗-algebra O(SUq(2)) of the quantum group SUq(2) decomposes into an orthogonal sum of projective Hop...

Actions of GL q (2, C) on C(1, 3) and its four dimensional representations Abstract. A complete classification is given of all inner actions on the Clif-ford algebra C(1, 3) defined by representations of the quantum group GL q (2, C), q m = 1 with nonzero perturbations. As a consequence of this classification it is shown that the space of invariants of every GL q (2, C)-action of this type, whi...
متن کاملON so 8 AND THE TENSOR OPERATORS
Physicists motivated by problems in high energy physics have for many years been groping their way toward a theory of tensor operators of simple lie algebras. Their work, calculations, insights, theorems, and guesses have appeared in the physics literature in a form not easily understood by either mathematicians or physicists [2, 3]. Extensive conversation with L. C. Biedenharn, a chief worker ...

The representation theory of the group U (1, q) is discussed in detail because of its possible application in a quaternion version of the Salam-Weinberg theory. As a consequence, from purely group theoretical arguments we demonstrate that the eigenvalues must be right-eigenvalues and that the only consistent scalar products are the complex ones. We also define an explicit quaternion tensor prod...
