In this note I prove the existence of extremal Sasakian metrics on S3-bundles over S2. These occur in a collection of open cones that I call a

We classify Hopf cylinders with proper mean curvature vector field in Sasakian 3-manifolds with respect to the Tanaka-Webster connection.

Let S be a compact Sasakian manifold which does not admit nontrivial Hamiltonian holomorphic vector fields. If there exists an EinsteinSasakian metric on S, then it is unique.

The object of the present paper is to study the extended generalized φ-recurrent trans-Sasakian manifold and its various geometric properties.

This paper consists of two main sections. In the first part, we give some general information about almost contact manifold, α−Sasakian, β−Kenmotsu and trans-Sasakian Structures on manifolds. second these structures were expressed tangent bundle with help lifts most forms tried to be obtained.

A gauge-invariant mass term for nonabelian gauge fields in two dimensions can be expressed as the Wess–Zumino–Witten (WZW) action. Hard thermal loops theory four at finite temperatures generate a screening some components of field. This terms WZW action using bundle complex structures (for Euclidean signature) or lightcones over Minkowski space. We show that dynamically generated three put with...

We study the dynamics of BPS D3–branes wrapped on a three–sphere in AdS5× L, so–called dual giant gravitons, where L is a Sasakian five–manifold. The phase space of these configurations is the symplectic cone X over L, and geometric quantisation naturally produces a Hilbert space of L2–normalisable holomorphic functions on X, whose states are dual to scalar chiral BPS operators in the dual supe...
