Hi! My name is Yang Chu(褚洋). I'm a final year Ph.D. student in the statistics department at UC Berkeley, working with Steve Evans and Alan Hammond. I completed a B.Sc. in Mathematics with honors and Applied Math & Statistics at Stony Brook University, where I was fortune to finish my honor thesis under the supervision of Robert Hough.
I'm interested in probability theory and stochastic processes, as well as connection with PDEs and game theory. A few projects I have been working on include:
1.Solution of the 15 puzzle problem, 2019. (arXiv: 1908.07106) (with Robert Hough) See also a report by Quanta
2.Non-Markovianity of $2K-B$ and a degeneration.} (with Lingfu Zhang). Electronic Journal of Probability 2025, Vol. 30, paper no. 195, 1-24. https://doi.org/10.1214/25-EJP1447. A short slides is avaliable here.
3.Exponential Absolute Minimizing extension and biased infinity Laplacian, (arxiv 2512.13664)
Forthcoming (see slides for a summary):
4.Feymann-Kac for infinity Laplacian and tug-of-war with killing.
5.Fisher-KPP equation with infinity Laplacian and branching tug-of-war.
