    The present work is a generalization of the work of Ribberfors and Reitz (2000 Eur. J. Phys. 21 151-7). These authors study a system consisting of a collar that is restricted to move in a path defined by a rod of some ...
  • Brasil, A; Colares, AG; Palmas, O (2010)
    To a given immersion i : M-n -> Sn+1 with constant scalar curvature R, we associate the supremum of the squared norm of the second fundamental form sup vertical bar A vertical bar(2). We prove the existence of a constant ...
