Strictly non-proportional geodesically equivalent metrics have $h_\text{top}(g)=0$
摘要:
设闭连通流形$M^n$上的黎曼度量$g$和$\bar g$至少在一点上测地线等价且严格不成比例.则$g$的测地流的拓扑熵为零。
英文摘要:
Suppose the Riemannian metrics $g$ and $\bar g$ on a closed connected manifold $M^n$ are geodesically equivalent and strictly non-proportional at least at one point. Then the topological entropy of the geodesic flow of $g$ vanishes.
