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…
Slant and Legendre Null Curves in 3-Dimensional Sasaki-like Almost Contact B-Metric Manifolds
Galia Nakova, Simeon Zamkovoy
Object of study in the present paper are slant and Legendre null curves in 3-dimensional Sasaki-like almost contact B-metric manifolds. For the examined curves we express the gener…
Null -Slant Curves in a Main Class of 3-Dimensional Normal Almost Contact B-Metric Manifolds
Galia Nakova
We introduce a new type of slant curves in almost contact B-metric manifolds, called -slant curves, by an additional condition which is specific for these manifolds. In this pap…
Totally umbilical radical screen transversal half lightlike submanifolds of almost contact B-metric manifolds
Galia Nakova
The present paper is a continuation of our previous work, where a class of half lightlike submanifolds of almost contact B-metric manifolds was introduced. We study curvature prope…
Radical screen transversal half lightlike submanifolds of almost contact B-metric manifolds
Galia Nakova
We introduce a class of half lightlike submanifolds of almost contact B-metric manifolds and prove that such submanifolds are semi-Riemannian with respect to the associated B-metri…
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…
The decomposition of almost paracontact metric manifolds in eleven classes revisited
Simeon Zamkovoy, Galia Nakova
This paper is a continuation of our previous work, where eleven basic classes of almost paracontact metric manifolds with respect to the covariant derivative of the structure tenso…
Holomorphic submanifolds of some hypercomplex manifolds with Hermitian and Norden metrics
Galia Nakova, Hristo Manev
In this paper we initiate the study of submanifolds of almost hypercomplex manifolds with Hermitian and Norden metrics. Object of investigations are holomorphic submanifolds of the…
Slant null curves on normal almost contact B-metric 3-manifolds with parallel Reeb vector field
Galia Nakova, Hristo Manev
In this paper we study slant null curves with respect to the original parameter on 3-dimensional normal almost contact B-metric manifolds with parallel Reeb vector field. We prove…
Totally umbilical radical transversal lightlike hypersurfaces of Kähler-Norden manifolds of constant totally real sectional curvatures
Galia Nakova
In this paper we study curvature properties of semi-symmetric type of totally umbilical radical transversal lightlike hypersurfaces and of a Kähler-Norde…
Radical transversal lightlike hypersurfaces of almost complex manifolds with Norden metric
Galia Nakova
In this paper we introduce radical transversal lightlike hypersurfaces of almost complex manifolds with Norden metric. The study of these hypersurfaces is motivated by the fact tha…
Some lightlike submanifolds of almost complex manifolds with Norden metric
Galia Nakova
In this paper we study submanifolds of an almost complex manifold with Norden metric which are non-degenerate with respect to the one Norden metric and lightlike with respect to th…
Some submanifolds of almost contact manifolds with Norden metric
Galia Nakova
In this paper we study submanifolds of almost contact manifolds with Norden metric of codimension two with totally real normal spaces. Examples of such submanifolds as a Lie subgro…
Almost Paracontact Manifolds
Galia Nakova, Simeon Zamkovoy
In this paper eleven basic classes of almost paracontact manifolds are introduced and some examples are constructed.
