That"s a much simpler way to put it than occurred to me, thank you!

comment A question about simple closed curves in finite dimensional Euclidean spaces
I guess you meant for $p$ to be degree $n$. (If the degree is smaller, the curve goes off to infinity, and if the degree is bigger, the number of intersections could go up.)

comment Finding commuting matrices
@JoonasIlmavirta That can't be right, since certainly scalar multiples of the identity commute with both $A$ and $B$. The feeling I have is rather that the eigenspaces of a matrix commuting with $A$ and $B$ should be big. Also, whether an eigenvalue is zero or not shouldn't matter, since $M$ will commute with $A$ and $B$ iff $\lambda I + M$ does.
