摘要

在文献[LiWang2001complete1,LiWang2001complete2]中,Li-Wang证明了对于满足Ric(n1)Ric\geqslant -(n-1)且谱底λ0(M)=(n1)24\lambda_0(M)=\frac{(n-1)^2}{4}的n维黎曼流形的分裂定理。对于满足Ric(n1)Ric\geqslant-(n-1)且体积熵h(M)=n1h(M)=n-1的n维紧流形MM,Ledrappier-Wang[LeW2010volent]证明了其万有覆盖M~\tilde{M}等距于双曲空间Hn\mathbb{H}^n。我们将证明Alexandrov空间的类似定理。
