Special vector fields on a compact Riemannian manifold

  • Grigorios Tsagas
Part of the Mathematics and Its Applications book series (MAIA, volume 350)

Abstract

The aim of the present paper is to prove that there exists no Killing vector field on a compact Riemannian manifold (M,g) with the property p(x) = 0 "; € M C {x 0} and p(x 0) < 0. This is an improvement of Yano’s result. It is also proved that dim K 1 (M, R) is not a topological invariant.
