WebWe characterizeη-Einsteink,μ-contact metric manifolds with associated scalars by considering symmetry,φ-symmetry, semisymmetry,φ- recurrent, and ﬂat conditions onk,μ-contact metric manifolds. The paper is organized as follows: In Section 2, we give some deﬁnitions and basic results. WebA contact manifold with ξ a Killing vector ﬁeld is called a K-contact manifold. One of the main purposes of the present paper is to prove the following theorem. Theorem 1.1. A contact Ricci soliton is shrinking and is Einstein K-contact. On the other hand, Boyer and Galicki [3] proved the following result. Theorem 1.2.
