Basic properties of such manifolds are obtained and general curvature identities are investigated. Next it is proved that if M is a quasi-para-Sasakian manifold of constant curvature K. Then K <= 0 and (z) if K = 0, the manifold is paracosymplectic, (ii) if K < 0, the quasi-para-Sasakian structure of M is obtained by a homothetic deformation of a para-Sasakian structure. Finally, an example of a 3-dimensional proper quasi-para-Sasakian manifold is constructed.eninfo:eu-repo/semantics/closedAccessquasi-para-Sasakian manifoldparacosymplectic manifoldconstant curvatureArticle122210217WOS:000493100800007N/AQ3
