Abstract
Exposed points, which take an indispensable part in the researches of some mathematics branches, have attracted increasing extensive exploration and discussion. In this paper, the sufficient and necessary conditions for exposed points of Orlicz function spaces equipped with the p-Amemiya norm are given. The obtained results complete and widen the characterization of exposed points of Orlicz function spaces.
