On the Existence of ,-Einstein Contact Metric Structures, co-oriented contact manifold .. Secondly, we apply this result to obtain important consequences. In particular, we give another proof of a theorem by Boyer and Galicki (Sasakian Geometry. Oxford Mathematical Monographs. Oxford University Press, Oxford (2008). xii+613pp.) on solutions to Goldberg’s

Metrics Induced by , on the Graph of ,-Smooth Functions and the Hopf Conjecture,a new proof of a theorem on metrics induced by . on the graph of 1-smooth function. Finally, we show that a metric induced by . on the graph of two smooth functions which are lifts on . does not have a positive sectional curvature.

Some Results on Warped Product ,-Ricci-Bourguignon Solitons,on warped product manifold whose potential vector field is conformal must be a quasi-Einstein manifold. As an application, we also study .-Ricci-Bourguignon solitons warped product standard static space-times and generalized Robertson-Walker space-times.
