Abstract:
For meromorphic circumferentially mean $p$-valent functions, an analog of the classical distortion theorem is proved. It is shown that the existence of connected lemniscates of the function and a constraint on a cover of two given points lead to an inequality involving the Green energy of a discrete signed measure concentrated at the zeros of the given function and the absolute values of its derivatives at these zeros. This inequality is an equality for the superposition of a certain univalent function and an appropriate Zolotarev fraction.
Keywords:
meromorphic function, $p$-valent function, lemniscate, Zolotarev fraction, symmetrization.
