About

Hi, my name is Lijun Ding and I am a fourth year PhD student in ORIE of Cornell University. You can find meĀ here.

This blog contains my original little discoveries in Optimization, Probability and Statistics when I am a student at the University of Chicago and Cornell University. Though some of them turns out to be special cases of some more general theorem, because of the specialty, the proof here is much simpler or more elementary. They are usually side product of my teaching assistance of a course, a course I took or my research.

Hope these discoveries will be intriguing and inspiring to you (sorry for the typos in the posts, please let me know if you find them).
