Weak almost contact structure with B-metric
Cornelia-Livia Bejan, Şemsi Eken Meriç
Corresponding to weak almost contact metric structures (defined recently by Rovenski and Wolak), we introduce and study here weak almost contact structures with B-metric, which gen…

Almost paracontact metric 3-dimensional Walker manifolds
Galia Nakova, Cornelia-Livia Bejan
In this paper we construct and study almost paracontact metric structures on a 3-dimensional Walker manifold with respect to a local basis only by the coordinat…

Almost para-Hermitian and almost paracontact metric structures induced by natural Riemann extensions
Cornelia-Livia Bejan, Galia Nakova
In this paper we consider a manifold with a symmetric linear connection which induces on the cotangent bundle of a semi-Riemannian metric $\overl…
