报告摘要：In this lecture we discuss Finsler metrics by warped product. We find equations that characterize locally projectively flat Finsler warped product metrics of constant flag curvature. Using the obtained equations we manufacture new locally projectively flat Finsler warped product metrics of vanishing flag curvature. These metrics contain the metric introduced by Berwald and the spherically symmetric metric given by Mo-Zhu. Then we discuss Finsler warped product metrics with isotropic S-curvature. We find the equation that characterize Finsler warped product metrics of isotropic S-curvature. Finally we explicitly construct infinitely many new non-spherically symmetric Finsler warped product metrics of isotropic S-curvature.
