On some Lie groups as 5-dimensional almost contact B-metric manifolds with three natural connections
Miroslava Ivanova, Hristo Manev
Almost contact manifolds with B-metric are considered. There are studied three natural connections (i.e. linear connections preserving the structure tensors) determined by conditio…

Natural connections with torsion expressed by the metric tensors on almost contact manifolds with B-metric
Mancho Manev, Miroslava Ivanova
On a main class of the almost contact manifolds with B-metric, it is described the family of the linear connections preserving the manifold's structures by 4 parameters. In this fa…
