Abstract: In this paper, we study projectively flat Finsler metrics defined by the Euclidean metric and related 1-forms. For this class of Finsler metrics, we find the necessary and sufficient condition to be Berwaldian. Then, we obtain the differential equations that characterize these metrics with vanishing Douglas curvature.
