Avi Zeff

I am a first-second-year PhD student at Columbia interested in number theory and arithmetic geometry. (Also, dead languages, music, and many other things.)

Spring 2022 I taught Calculus 2 (section 3); you can find some of the materials here.

Fall 2021 I was a TA for Calculus 3 with Inbar Klang.


I organized a seminar in fall 2021 on the proof of the norm residue isomorphism theorem; the website can be found here.


Note: all of these are still in flux and may (in fact, definitely do) contain at least some errors. Use at your own risk. (Also if you catch errors, or find one of the places where I have written something to the effect of ??? and moved on and have an explanation, please let me know!)

I have many opinions, but I am always soliciting more; if you have any good ones feel free to send them to me. (Responses not guaranteed.)
