关于A型仿射Schur代数II

On the affine Schur algebra of type A II

Dong Yang

摘要:

通过研究仿射Schur代数$\widetilde{S}(n,r)$的中心化子代数,证明了$\widetilde{S}(n,r)$是Noether代数,并确定了它的中心.假设$n\geq r$,证明了$\widetilde{S}(n+1,r)$与$\widetilde{S}(n,r)$是Morita等价的,并且Schur函子在一定条件下是等价的.

英文摘要:

By studying certain kind of centralizer algebras of the affine Schur algebra $\widetilde{S}(n,r)$ we show that $\widetilde{S}(n,r)$ is Noetherian and we determine its center. Assuming $n\geq r$, we show that $\widetilde{S}(n+1,r)$ is Morita equivalent to $\widetilde{S}(n,r)$, and the Schur functor is an equivalence under certain conditions.
