Resumo
This dissertation is based about two works on quase Einstein manifolds. The
first, published in 2000, by M. C. Chaki and R. K. Maity, on quase Einstein
manifolds which are not conformally flat, and they determine sufficient condition
so that the same ones are conformally flat. Already the second work,
published by U. C. De and Gopal Chandre Ghosh, in 2004, establish a relation
between the manifolds of amost constant curvature and the quasi Einstein
manifolds, find necessary and sufficient conditions for a quasi Einstein manifolds
to be of almost constant curvature, in follow prove an existence theorem
on quase Einstein manifolds with other such manifolds like weak symmetries
and semi-symmetries Ricci.
