| Outline of Final Research Achievements |
Finsler geometry is the differential geometry of smooth family Hessian manifolds or Kahlerian manifolds parameterized by base points corresponding to real or complex category. In this research, we have investigated real or complex Finsler geometry by using the averaging method, namely, we consider the averaged metrics and averaged connection obtained by the integral along the fibers. In particular, we have investigated the conformal geometry in real category, and we have obtained a characterization of conformal flatness of Finsler metrics. In complex category, we have introduced the notion of Rizza-negativity of holomorphic vector bundles, and further, we investigated the ampleness or negativity of holomorphic vector bundles in terms of the curvature of Rizza-structure which is naturally defined in the tautological line bundles.
