Abstract: We study the sets of uniqueness of areally mean p-valent functions in the unit disc. Namely, if $ f(z)$ is in this class and has the same angular limit in a set E on the boundary of the unit disc, we prove that if p is small compared to the size of E then $ f(z)$ is constant. We then construct an areally mean p-valent function which shows that some condition on the size of the set E must be imposed.
