关于Demazure模的融合积分解的注记

A note on the fusion product decomposition of Demazure modules

R. Venkatesh, Sankaran Viswanath

摘要:

我们解决了$E^{(1)}_{6, 7, 8}, F^{(1)}_4$和$E^{(2)}_{6}$情况下高阶仿射Demazure模的融合积分解定理,从而完成了Chari等人(J. Algebra,2016)和Kus等人(Represent. Theory,2016).我们得到了一个新的组合证明的关键事实,这是在Chari等人。(同上),来证明这个分解定理我们对这个关键事实给出了一个无案例的统一证明。

英文摘要:

We settle the fusion product decomposition theorem for higher-level affine Demazure modules for the cases $E^{(1)}_{6, 7, 8}, F^{(1)}_4$ and $E^{(2)}_{6}$, thus completing the main theorems of Chari et al. (J. Algebra, 2016) and Kus et al. (Represent. Theory, 2016). We obtain a new combinatorial proof for the key fact, that was used in Chari et al. (op cit.), to prove this decomposition theorem. We give a case free uniform proof for this key fact.
