On weakly φ -symmetric Kenmotsu Manifolds

Shyamal Kumar Hui (2012)

Acta Universitatis Palackianae Olomucensis. Facultas Rerum Naturalium. Mathematica

Similarity:

The object of the present paper is to study weakly φ -symmetric and weakly φ -Ricci symmetric Kenmotsu manifolds. It is shown that weakly φ -symmetric and weakly φ -Ricci symmetric Kenmotsu manifolds are η -Einstein.

On weakly cyclic Ricci symmetric manifolds

A. A. Shaikh, Sanjib Kumar Jana (2006)

Annales Polonici Mathematici

Similarity:

We introduce a type of non-flat Riemannian manifolds called weakly cyclic Ricci symmetric manifolds and study their geometric properties. The existence of such manifolds is shown by several non-trivial examples.
