Abstract: |
In this paper, we study submanifolds in Finsler manifold M. By using tangent curvature and normal curvature, which are introduced in [23,24], we derive a new second variation formula for a geodesic γ in Finsler manifold, and then obtain many relation between geometric invariants and topological invariants of Finsler submanifolds, which are generalizations of the results described in [4]. |
Key words: sur-tangent curvature normal curvature second variation formula compact |
