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).
