似乎并不高。只是说他们给出了详细的证明说明。用了一些新思想但这些新思想只是重新证明了一些定理从而使整个证明更容易理解。这样一说似乎验证了丘成桐的说法---曹朱写的三百叶证明就像教科书。大家都知道，教科书往往与原来论文写的不一样，也可以有新思想，但不能算原创。
Cao huai-dong and Zhu Xiping have recently given a complete and detailed account of the proof of Poincare conjecture based on the work of Perelman and earlier work of others. It’s very nice to have such an account written by two outstanding people in the field of Ricci flow. They also introduced ideas of their own which makes the proof easier to understand. This includes a new proof for the uniqueness of solutions on complete manifolds, and different idea for doing the backwards blowup in time and proof of the canonical neiborhood theorem based on results of Zhu and Chen on expanding solitons.
