초록

In the present paper we study 3-dimensional contact metric manifolds with 𝜑Q = Q𝜑 admitting generalized Ricci solitons and generalized gradient Ricci solitons. It is proven that if a 3-dimensional contact metric manifold satisfying 𝜑Q = Q𝜑 admits a generalized Ricci soliton with non zero soliton vector field V being pointwise collinear with the characteristic vector field ξ, then the manifold is Sasakian. Also it is shown that if a 3-dimensional compact contact metric manifold with 𝜑Q = Q𝜑 admits a generalized gradient Ricci soliton then either the soliton is trivial or the manifold is flat or the scalar curvature is constant.
