On the concircular curvature of a \((\kappa,\mu,\nu)\)-manifold
In the present paper, \((\kappa,\mu,\nu)\)-contact metric 3-manifolds with certain conditions such as Ricci flat, or Einstein but not Sasakian or \(\triangledown Z=0\), where \(Z\) is the concircular curvature tensor, \(Z(\xi. X). Z=0\), where \(Z\) acts as a derivation on \(Z\) are investigated. The results are new and provide a valuable contribution to the field of contact geometry.
