Lengths of closed geodesics for certain warped product metrics and nearly round metrics on spheres

Abstract We study warped product metrics on spheres and prove that the shortest length of closed geodesics for such metrics can be bounded above by its volume, under suitable assumptions on the warping function. As a result, we manage to extend the classical inequality on two spheres between the sho...
