Periodic geodesics in singular spaces
We extend the classical result of Lyusternik and Fet on the existence of closed geodesics to singular spaces. We show that if X is a compact geodesic metric space satisfying the CAT(κ) condition for some fixed κ>0 and πn(X)≠0 for some n>0 then X has a periodic geodesic. This condition is satis...
