Hi! My name is Peihang Wu (吴沛航). I am currently a postdoc at Beijing International Center for Mathematical Research (BICMR), Peking University. Before coming to BICMR, I received my Ph.D degree in August 2024 at the University of Minnesota (advisor: Kai-Wen Lan). Before that, I was an undergraduate student at Fudan University.
I am interested in number theory and related topics. Currently, I am thinking about problems related to integral models of Shimura varieties and their compactifications.
Here is my CV (last updated: Nov. 24th, 2025).

This is essentially a "major revision" of my PhD thesis (submitted in August 2024) with the same title but significantly improved main results. A sequel to it is in preparation. The PDF version above is more up-to-date than the one on arXiv; and I will update whenever I find typos. Current version: Fixed some typos and minor errors (see especially 1.10, 4.20, 4.32 and 4.57).
