摘要:In this lecture we discuss the warped structures of Finsler metrics. We obtain the differential equation that characterizes the Finsler warped product metrics with vanishing Douglas curvature. By solving this equation, we obtain all Finsler warped product Douglas metrics. Some new Douglas Finsler metrics of this type are produced by using known spherically symmetric Douglas metrics. We also refine and improve Chen-Shen-Zhao equations characterizing Finsler warped product metrics of scalar flag curvature. In particular,we find equations that characterize Finsler warped product metrics of constant flag curvature. Then we improve Chen-Shen-Zhao result on characterizingEinstein Finsler warped product metrics. As its application we construct explicitly many new warped product Douglas metrics of constant Ricci curvatureby using known locally projectively flat spherically symmetric metrics of constant flag curvature.
