刚刚看到曹、 朱有关 Poincaré 猜想的论文的修改版 (math.DG/0612069)， 其中摘要 (Abstract) 及介绍 (Introduction) 部分在语气上做了明显改动。 在新版的摘要部分中原先的 “封顶” (crowning achievement) 一词不再出现， 且整个工作被定位为了对 Hamilton 和 Perelman 的证明的 “详尽阐述” (detailed exposition)。 新版的介绍部分则不仅不再强调 “第一” (first written account)， 且明确表示所有的贡献都归功于 Hamilton 和 Perelman (full credit ... goes to ...) (这其实有点过誉)。

旧版的摘要部分：

In this paper, we give a complete proof of the Poincar´e and the geometrization conjectures. This work depends on the accumulative works of many geometric analysts in the past thirty years. This proof should be considered as the crowning achievement of the Hamilton-Perelman theory of Ricci flow.

新版的摘要部分：

In this paper, we provide an essentially self-contained and detailed account of the fundamental works of Hamilton and the recent breakthrough of Perelman on the Ricci flow and their application to the geometrization of three-manifolds. In particular, we give a detailed exposition of a complete proof of the Poincar´e conjecture due to Hamilton and Perelman.

旧版的介绍部分：

In this paper, we shall present the Hamilton-Perelman theory of Ricci flow. Based on it, we shall give the first written account of a complete proof of the Poincar´e conjecture and the geometrization conjecture of Thurston. While the complete work is an accumulated efforts of many geometric analysts, the major contributors are unquestionably Hamilton and Perelman.

新版的介绍部分：

This is a revised version of the article that originally appeared in Asian J. Math., 10(2) (2006), 165–492. In July, we received complaint from Kleiner and Lott for the lack of attribution of their work caused by our oversight in the prior version; we have apologized and acknowledged their contribution in an erratum to appear in December 2006 issue of the Asian Journal of Mathematics. In this revision, we have also tried to amend other possible oversights by updating the references and attributions. In the meantime, we have changed the title and modified the abstract in order to better reflect our view that the full credit of proving the Poincare’s conjecture goes to Hamilton and Perelman. We regret all the oversights occurred in the prior version and hope that this revision will right these inattentions. Other than these modifications mentioned, the paper remains unchanged.

In this paper, we shall present the Hamilton-Perelman theory of Ricci flow. Based on it, we shall give a detailed account of complete proofs of the Poincar´e conjecture and the geometrization conjecture of Thurston. While the results presented here are based on the accumulated works of many geometric analysts, the complete proof of the Poincar´e conjecture is due to Hamilton and Perelman.

从这个摘要看来他们不是很肯定可以完全证明几何化猜想

为人要低调。
当初要是这样子，就不会搞到灰头土脸了

百分只三十的（不论是谁划分的）蛋糕就这样飞了，全部都成为Hamilton和Perelman的盘中餐
当时在国内轰轰烈烈捧Poincaré 猜想贬低Godbach猜想的戏（虽然Godbach猜想本身就是大大不如Poincaré 猜想）也就完全成为为别人跑龙套了
当事人都来了个大转弯，不知道其他一些人会不会继续坚持说“中国人把Perelman踢上领奖台”了。

For the authors, the revision is an embarrassment.

For others, it was the failure of a premeditated robbery.

=========================================================

That's not completely true. One fact, which is different from 100 years ago, is that agressiveness usually pays off in academic circles. This statement applies to people like Lee, Yang, Ting, Yau....
It is not necessarily a bad thing.

这纯粹是个人性格问题了，学术界张扬的很张扬，低调的很低调，很难说谁是谁非。学术圈也是一个小社会，什么样的人都有。

高调必须建立在真实之上，如果操纵媒体夸大甚至歪曲事实那就不好了
