Some characterizations for a (k, μ)-paracontact metric manifold to be an η-Einstein manifold.

In this paper we introduce the curvature tensors of (k,µ)-paracontact manifold satisfying the conditions R · W 0 = 0, P · W 0 = 0, e Z · W*0 = 0, e C · W 0 = 0 and W 0 · W 0 = 0. According these cases, (k, µ)-paracontact manifolds have been characterized such as -Einstein. [ABSTRACT FROM AUTHOR]
