Hi, my name is Likun Xie. I’m a second year PhD student in UIUC. I’m recently interested in commutative algebra, algebraic geometry and homotopy theory. I obtained my MSc in maths in the University of Warwick (2019) and BSc in maths and physics in the University of Manchester (2016-2018).

Besides maths, I like to self-analyze my mind, sometimes with the inspiration from other philosophers and psychologists. I also play the classical guitar. I love its warm, beautiful and touching sound, varying tones and polyphony. My best friend is bear.

This blog is for some casual maths writing or some thoughts in daily life. I try to make sure my writing in maths is as careful as I can. If you see any errors or typos, or you have any thoughts or suggestions that you’d like to share, please let me know! You can reach me either by email or comment on my blog.

This blog has recently changed theme to focus more on commutative algebra!
