Generalized quasi-Einstein manifolds with harmonic Weyl tensor
Generalized quasi-Einstein harmonic Weyl tensor
2011/2/28
In this paper we introduce the notion of generalized quasi–Einstein manifold, which
generalizes the concepts of Ricci soliton, Ricci almost soliton and quasi–Einstein manifolds. We prove that a compl...
Some triviality results for quasi-Einstein manifolds and Einstein warped products
quasi-Einstein manifolds Einstein warped products
2010/11/9
In this paper we prove a number of triviality results for Einstein warped products and quasi-Einstein manifolds using different techniques and under assumptions of various nature. In particular we ob...
Conformally warped manifolds and quasi-Einstein metrics
Conformally warped manifolds quasi-Einstein metrics

Smooth metric measure spaces have been studied from the two different perspectives of Bakry-\'Emery and Chang-Gursky-Yang, both of which are closely related to work of Perelman on the Ricci flow. The...
On a class of generalized quasi-Einstein manifolds
Einstein, quasi-Einstein generalized quasi-Einstein pseudo Ricci-symmetric R-harmonic manifold

In this study, we find the necessary conditions in order that
a special class of generalized quasi-Einstein manifolds to be pseudo Riccisymmetric
and R-harmonic. We also consider these type manifold...
