Abstrakt:
The equation $Z(x) = [ \int_0^\infty p(q) Z(qx) dq ]^2$ looks simple. It comes from physics and represents a fixed point in the stochastics of the turbulent energy cascade. Numerical simulations show that general solutions exist. To the best of my knowledge, a general analytic solution is still missing. This is the challenge for the audience.
