AMS Seminar w/ Ed Scheinerman (JHU-AMS) on Zoom

Title: Finding a Compositional Square Root of Sine

Abstract: We consider the following type of problem: Given a function g : A ! A, find a
function f such that g = f  f . We are especially interested in the case sin : R ! R, but
consider the problem more broadly with results for other functions g defined on other sets
A. This is joint work with JHU undergraduate Tongtong Chen. And, despite appearances
to the contrary, this is a graph theory talk.
