On the isometry groups of Sasakian manifolds
\S 1. IntroductionThe dimension of the isometry group of an m-dimensional Riemannian manifold $(M, g)$ is equal to or smaller than $m(m+1)/2$.The maximum is attained if and only if $(M, g)$ is of constant curvature and one of the follow- ing manifolds: a sphere $S^{m}$ , a real projective space …
