Symmetric cut loci in Riemannian manifolds. (English) Zbl 0563.53037

Let M be a compact Riemannian manifold with \(H_ 1(M,Z)=0\). We show that, for a point \(p\in M\), the cut locus and conjugate locus of p must intersect if M admits a group of isometries which fixes p and has principal orbits of codimension at most 2. This is a classical theorem of S. B. Myers [Proc. Natl. Acad. Sci. USA 21, 225-227 (1935; Zbl 0011.22601)] in the case when M has dimension 2.
