Pseudosymmetric and Weyl-pseudosymmetric ( κ , μ ) -contact metric manifolds N. Malekzadeh; E. Abedi; U.C. De — 2016 Archivum Mathematicum In this paper we classify pseudosymmetric and Ricci-pseudosymmetric ( κ , μ ) -contact metric manifolds in the sense of Deszcz. Next we characterize Weyl-pseudosymmetric ( κ , μ ) -contact metric manifolds.
