设H是域k上的dykin型Dn遗传代数,且?H是H的簇范畴。假设n≥5,T和T‘是倾斜的对象?h.证明了簇倾斜代数Γ=End?H(T)OP同构于Γ‘=End?H(T‘)op当且仅当对某些整数i和j T=τiT’或T=στj T‘,其中τ是Auslander-Reiten变换,σ是?第4节中定义的H。
Let H be a hereditary algebra of Dynkin type D n over a field k and ? H be the cluster category of H. Assume that n ≥ 5 and that T and T′ are tilting objects in ? H . We prove that the cluster-tilted algebra Γ = End? H (T)op is isomorphic to Γ′ = End? H (T′)op if and only if T = τ i T′ or T = στ j T′ for some integers i and j, where τ is the Auslander–Reiten translation and σ is the automorphism of ? H defined in Section 4.
