Hi, my name is Likun Xie. I’m a first year PhD student at UIUC. I’m interested in algebraic topology, homotopy theory, algebraic geometry and higher categories. I previously was a maths student in the University of Warwick (2019) and an undergraduate in maths and physics in the University of Manchester (2016-2018).

This blog is mostly for holiday entertainment where I posted some notes in maths in my spare time.
