About

Postdoc at UIUC. Previously at Berkeley (PhD) and Stanford (undergrad). My research is in algebraic geometry (de Rham-Witt complexes), but I'm also interested in number theory, finite group theory, etc.

When $f(z) = 1/z$ and $g(z) = 1-z$, why is $f \circ g \circ f \circ g \circ f \circ g (z) = g \circ f \circ g \circ f \circ g \circ f (z) = z$?
