2025丘赛几何与拓扑丘赛参赛感悟
Published:
我报名参加了丘成桐大学生数学竞赛的“分析与方程”和“几何与拓扑”两个方向。分析与方程的赛题与以往大不相同，从难度上来说，甚至可能低于2010年创赛之处的水平。虽然我能做一部分题目（如果按前几年的题目来考，很可能一道也做不出），但还是跟一些基础好的选手有很大差距，没有得奖。但幸运的是，我赛前投入很多时间准备几何与拓扑方向，得到了笔试优胜奖，但没能进决赛，也很让我满意了，这足够作为一个我在几何与拓扑方向的专业水平的证明。 Read more
我的第一篇博客笔记
Published:
这是我的第一篇博客笔记，就记录前几天的一个学习感触吧。今天的AI的确可以帮助学习和研究了。我在读Manolescu写的综述时，看到他说“Moise在1952年证明了三维流形的拓扑、P.L.、光滑三个范畴等价”，但如果去查Moise的论文，只能看到他证明了拓扑和P.L.两个范畴的确是等价的。我再去查更多三维流形的专著，它们也都很含糊的讲这个事实，但也没给更多的参考资料。 Read more
