斯克在《“破解”庞加莱猜想：中大忽悠到何时？》中质疑李思廉得知朱熹平教授破解国际数学难题“庞加莱猜想”。英文维基百科已经写的很清楚：

http://en.wikipedia.org/wiki/Poincar%C3%A9_conjecture

Huai-Dong Cao and Xi-Ping Zhu published a paper in the June 2006 issue of the Asian Journal of Mathematics giving a complete proof of the Poincaré and geometrization conjectures.[18] They initially claimed the proof as their own achievement based on the "Hamilton-Perelman theory", but later retracted the original version of their paper, and posted a revised version, in which they referred to their work as the more modest "exposition of Hamilton–Perelman's proof".[19] They were also forced to publish an erratum disclosing that they had failed to cite properly the previous work of Kleiner and Lott published in 2003. In the same issue, the AJM editorial board issued an apology for what it called "incautions" in the Cao–Zhu paper.

佩雷尔曼破解庞加莱猜想举世皆知。捐款者作为一个数学系的毕业生也被如此忽悠，让其母校也不光彩。
