Abstract: An effective representation is obtained for rational functions all of whose critical points, apart from $g-1$, are simple and their corresponding critical values lie in a four-element set. Such functions are described using hyperelliptic curves of genus $g\geqslant1$. The classical Zolotarëv fraction arises in this framework for $g=1$.
Bibliography: 8 titles.
Keywords: rational approximation, Zolotarëv fraction, Riemann surfaces, Abelian integrals.
