Congrats Cheih-Yu Chang!

Congrats to C. Y. Chang, a number theorist working on transcendence in function field arithmetic (FFA)! He has been awarded a silver medal by the International Congress of Chinese Mathematicians. See this link for more.

He and his collaborators have determined all algebraic relations among various objects such as the Carlitz zeta values, and special values of an analog of the gamma function in FFA, among other things. Nothing like their work has been done yet for number fields. 

Those interested in these things should again see my notes on log-algebraicity (linked just below) where some of these things are discussed briefly with references. I also recommend an internet search for Chang and his collaborators. It’s fairly easy to get a good sense of their work from the introductions to their papers.
