量子群U_q(f(K))的局部有限子代数的稳定理想

The Stable Ideal of the Locally Finite Subalgebra of Quantum Group U_q(f(K))

利用量子群U=U_q(f(K))的表示理论及其局部有限子代数F(U)的子模结构,证明了U_q(f(K))的局部有限子代数F(U)的任一非零理想均可由若干个具有不同权的最高权向量的和生成.

In this paper,by using the representation theory and structure of the locally finite subalgebra F(U) of the quantum group U = U_q(f(K)),we prove that every non-zero U-stable ideal of F(U) can both be generated by a sum of some highest weight vectors with distinct weights.
