Abstract

We consider generalized (κ,μ)-paracontact metric manifolds satisfying certain flatness conditions on the -projective curvature tensor. Specifically, we study ξ--projectively flat and -projectively flat generalized (κ,μ)-paracontact metric manifolds and, further, ϕ--projectively symmetric generalized (κ-1,μ)-paracontact metric manifolds. We prove that they are characterized by certain structures whose properties are discussed in some detail.
