Finding a Compositional Square Root of Sine


Program: Applied Mathematics and Statistics

We consider the following type of problem: Given a function g: A → A, find a function f : A → A 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.
