Let $f(x,y)$ be a symmetric rational function and a formal group law.
$G(x + y) = f(G(x),G(y)) $
Consider the equation
$$ h(2x) = f(h(x),h(x)) = A(h(x)) $$
This equation has many solutions.
Compute a solution to that equation with koenigs function, and call the solution $k(x)$.
So
$$k(2x)...
Some of us might find such a comment offensive. Of course, topology is not just point-set topology. Most mathematicians aren't very interested in point-set topology.
@LeakyNun It kinda depends. Someone can mean boring to say "I don't personally enjoy X", in which case it's just like, you do you. But sometimes that can have an undertone (or at least sound like it has an undertone) of passing judgment on other folk's interests
