In this study,
we consider weakly symmetric and weakly Ricci-symmetric (k, μ)-contact metric manifolds. We find necessary
conditions in order that a (k, μ)-contact
metric manifold be weakly symmetric and weakly Ricci symmetric.

Bu
çalışmada, zayıf simetrik ve zayıf Ricci-simetrik (k, μ)-değme metrik manifoldları göz önüne aldık. (k, μ)-değme metrik manifoldların zayıf
simetrik ve zayıf Ricci-simetrik olması için gerekli şartları bulduk.
