On the cut Locus and the Focal Locus of a Submanifold in a Riemannian Manifold II


Hukum Singh


Let $M$ be a compact connected Riemannian manifold and let $L$ be a compact connected submanifold of $M$. We show that if a point $x$ is a closest cut point of $L$ which is not a focal point of $L$, then two different minimizing geodesics meet at an angle of $\pi$ at $x$. We also generalize some of the results of [9].
