Yifeng Huang

I am a PhD candidate in the Department of Mathematics at the University of Michigan–Ann Arbor. My advisor is Michael Zieve. I am interested in a variety of concrete problems in algebraic geometry, number theory and combinatorics. I have also worked on arithmetic dynamics. I am graduating in April 2022 and I am currently looking for a postdoctorial position.

Here is my CV and my research statement.

Research Talks (upcoming and past)


I am teaching MATH 115: Calculus I in Fall 2021. If you are my student, please refer to your canvas site for more information.

I have previously taught MATH 105: Data, Functions and Graphs, MATH 115: Calculus I, MATH 116: Calculus II and EECS 203: Discrete Mathematics.

Non-research writings

  • Handwritten notes on mass formulae predicting the distribution of number field discriminants, following a paper by Manjul Bhargava, for the final presentation of a topic course on arithmetic statistics in Winter 2020. It contains an attempt to explain a subtle mismatch in the quadratic case.
  • Expository notes on quadratic forms and quadratic fields.
  • Notes on elliptic curves with complex multiplication, attempting to fix a gap in Silverman's Advanced Topics in the arithmetic of elliptic curves, Theorem II.4.1.
  • Notes on abelian varieties, written as final projects of the algebraic geometry course in Winter 2016 and the abelian variety course in Fall 2017.
  • Two introductory notes on Chern classes. via Schubert calculus, via differential geometry
