摘要

对于Dynkin箭图,我们找到了Laurent多项式 X~a,cb(v)\widetilde{X}_{a, c}^{b}(v),并利用 X~a,cb(v)\widetilde{X}_{a, c}^{b}(v)\mz[v,v1]\mz[v, v^{-1}] 上构造Hall代数 \hcv(\cc(\cp))\hc_v(\cc(\cp)),其中 X~a,cb(\mfq)\widetilde{X}_{a, c}^{b}(|\mf_q|) 是Bridgeland使用的结构常数。Laurent多项式 X~a,cb(v)\widetilde{X}_{a, c}^{b}(v)A1A_1 情形被显式给出。作为一个应用,我们得到了与Dynkin箭图相关的对于任意 t0,±1t\not=0,\pm1 的完整量子群 Ut(\sg)U_t(\sg)
