Solving $f(x) = f(g(x)),h(x)$ for $f$












0














How do I go about solving equations of the form



$f(x) = f(g(x)),h(x)$



for the function f, given functions $g$ and $h$? Is there maybe some integral transform that I could use? When $h(x)$ is constant, then this would be Schröder's equation, but in my case $h(x)$ is not constant.



If this can be solved, how would you tackle the more complicated problem of solving



$f(x) = sum_i f(g_i(x)),h_i(x)$



for the function $f$, given the finite sets of functions ${g_i}$ and ${h_i}$?
