Some examples of Finsler metrics with special curvature properties (Q6631481)

The authors construct new non-projectively flat Finsler warped product metrics with zero flag curvature. They also construct new generalized Douglas-Weyl metrics which are nontrivial in the sense that these metrics are neither Douglas metrics nor Weyl metrics. In Theorem 1.1 they construct such metrics having constant positive sectional curvature and in Theorem 1.2 they construct such metrics having constant negative sectional curvature
