Abstract
In this paper we obtain criteria of stability for ηEinstein k-contact manifolds, for Sasakian manifolds of constant xs03D5-sectional curvature and for 3-dimensional Sasakian manifolds. Moreover, we show that a stable compact Einstein contact metric manifold M is Sasakian if and only if the Reeb vector field ξ minimises the energy functional. In particular, the Reeb vector field of a Sasakian manifold M of constant xs03D5-holomorphic sectional curvature +1 minimises the energy functional if and only if M is not simply connected.
