设聪慧矩阵的2重仿射A[2]的广义交矩阵代数为聪慧矩阵的2重仿射A[2]。讨论了<s:2> <s:2> <s:2> <s:2> <s:2>的根系、非简并不变双线性形式和Weyl群。
Let 𝔤𝔦𝔪(A [2]) be the generalized intersection matrix algebra associated to the 2-fold affinization A [2] of a simply-laced Cartan matrix . The root system, nondegenerate invariant bilinear form, and Weyl group of 𝔤𝔦𝔪(A [2]) are discussed.
