证明了具有非零参数p,q∈C的2个A2 ~仿射Hecke代数hp&hq在p≠q和pq≠1时不同构(定理3.1)。然而它们在局部是同构的。更确切地说,我们证明了商代数Hs,qand Ht是同构的,只要n,q=Nt,p对于A2 ~(定理2.4)。
We prove that two affine Hecke algebras Hpand Hqof type A2˜ with nonzero parameters p,q∈C are not isomorphic whenever p≠q and pq≠1 (Theorem 3.1). However they are isomorphic locally. More precisely, we prove that the quotient algebras Hs,qand Ht,pare isomorphic provided that Ns,q=Nt,pfor type A2˜ (Theorem 2.4).
