Yinan Zhang

I am now at the Mathematical Sciences Institute at the Australian National University.

I remain affiliated with the University of Sydney as an honorary associate in the School of Mathematics and Statistics.

Research Interests

My PhD was on p-adic verification of class groups through computing p-adic L-functions. I am interested in various aspects of p-adic number theory, including p-adic Galois representation and class field theory.

I am a member of the Computational Algebra research group.
