About Me

Hi, I’m Yijie Miao (Chinese Name: 苗祎杰, Wade-Giles romanization: I-chieh Miao), a student in the Department of Mathematics at Southeast University. I have conducted some research on gradient estimates in general metric spaces and nonlinear equations under different geometric flows, and my paper entitled “Two methods of gradient estimates for the Lichnerowicz equation and their comparison” has been accepted by the Taiwanese Journal of Math. Simultaneously, I have also gained in-depth knowledge and understanding of parabolic equations under curvature flows, the Moser iteration method, and improvements to gradient estimation methods based on integral curvature. Specifically, I also enjoy playing Chinese chess, Go, and tennis.

该如何描述我对基础数学的感觉呢? 我想会是深沉而执着的,并非浅尝辄止的。它就像徒步者对山川的眷恋,在踏遍每一寸土地后,心中燃起了征服珠穆朗玛峰的雄心。我无意于四处流连,也无心于沿途风景,只愿将全部心血毫无保留地倾注于此,以此作为叩开那扇通往数学圣殿的庄严大门的唯一钥匙。

Collaborative Study Materials

In the spirit of open-source learning, this space serves as a collective archive for mathematical excellence. I welcome submissions of exceptional course notes and resources—help us fill the gaps or provide new insights for fellow students and researchers.

本专栏旨在收录整理各类高质量的数学课程资源,涵盖本科、研究生课程,以及部分专题研讨会和精选的在线课程(中科大的孙天阳学长整理了更多内容,已附上链接,这里更多的是我学习过或想了解的内容)。后续与链接相关内容的个人学习心得与整理将更新至此,以便回顾与查阅。这个专栏的成长离不开大家的支持。如果你在学习过程中发现了任何优秀的课程(本校、外校、网络),都欢迎投稿给我。让我们一起,把这里变成一个汇集精华学习资源的宝地!再次感谢同学们的支持,更要感谢所有讲授课程的老师们!(如有侵权或不宜上传的内容,请及时邮件联系,谢谢!)
