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 characterizing Einstein
Finsler warped product metrics. As its application we construct
Explicitly many new warped product Douglas metrics of constant Ricci
curvature by using known locally projectively flat spherically symmetric
metrics of constant flag curvature.
