چکیده
We define a set of orthogonal functions on the complex projective space CPN−1, and compute their Clebsch-Gordan coefficients as well as a large class of 6–j symbols. We also provide all the needed formulae for the generation of high-temperature expansions for U(N)-invariant spin models defined on CPN−1.

Generalized W∞ Higher-Spin Algebras and Symbolic Calculus on Flag Manifolds
We study a new class of infinite-dimensional Lie algebras W∞(N+, N−) generalizing the standard W∞ algebra, viewed as a tensor operator algebra of SU(1, 1) in a grouptheoretic framework. Here we interpret W∞(N+, N−) either as an infinite continuation of the pseudo-unitary symmetry U(N+, N−), or as a “higher-U(N+, N−)-spin extension” of the diffeomorphism algebra diff(N+, N−) of the N = N++N− tor...

We study the Chern-Simons CP (N) models with a global U(1) symmetry and found the self-dual models among them. The Bogomolnyi-type bound in these self-dual models is a nontrivial generalization of that in the pure CP (N) models. Our models have quite a rich vacuum and soliton structure and approach the many known gauged self-dual models in some limit. PACS number(s): 11.15.-q, 11.10.Kk, 11.10.L...
متن کاملCharacter Expansions for the Orthogonal and Symplectic Groups
Formulas for the expansion of arbitrary invariant group functions in terms of the characters for the Sp(2N), SO(2N + 1), and SO(2N) groups are derived using a combinatorial method. The method is similar to one used by Balantekin to expand group functions over the characters of the U(N) group. All three expansions have been checked for all N by using them to calculate the known expansions of the...

We review the solutions of O(N) and U(N) quantum field theories in the large N limit and as 1/N expansions, in the case of vector representations. Since invariant composite fields have small fluctuations for large N , the method relies on constructing effective field theories for composite fields after integration over the original degrees of freedom. We first solve a general scalar U(φ) field ...
