Abstract:
We show how Zoll metrics of positive Gauss curvature induces a Finsler metric of constant flag curvature K=1 on the 2-dimensional sphere. We also show how to introduce local coordinates on the manifold of geodesics of a sphere endowed with Zoll metric and write down explicitly the induced Finsler fundamental function. Our study shows that the manifold of geodesics of a Zoll metric with positive Gauss curvatures naturally inherits a Finsler structure of constant flag curvature K=1.
