Abstract

The object of this paper is to introduce the notion of extended generalized /-recurrency
to Sasakian manifolds and study its various geometric properties with the existence by an
interesting example. Among the results established here it is shown that an extended generalized
/-recurrent Sasakian manifold is an Einstein manifold. Further, we study extended generalized
T–/-recurrent Sasakian manifold and obtain the results which reveal the nature of its associated
1-forms. Finally, an example of a 3-dimensional extended generalized /-recurrent Sasakian manifold
which is neither /-recurrent nor generalized /-recurrent is constructed for illustration.
