Could someone give me some hint about a possible method to find the function $f$ which solve this equation: $f(H^2)=\alpha f(H)$ where $\alpha$ a constant with $\alpha \in C$ and: $H=\begin{bmatrix} a_{11} & a_{12} \\ a_{21} & a_{22} \end{bmatrix}$ a matrix with complex elements?

    @Martin Argerami: I agree. Obviously the trivial solution $f=0$ has to be rejected.2012-07-02
