Design, analysis and implementation of electronic test for knowledge evaluation in the course of Information Technologies for pharmaceutical students
Hristo Manev, Mancho Manev
The increased usage of the information technologies in everyday life and especially in education leads to demands for new forms of teaching, studying and appropriate examination an…
Space-like and time-like hyperspheres in real pseudo-Riemannian 4-spaces with almost contact B-metric structures
Hristo Manev
There are considered 4-dimensional pseudo-Riemannian spaces with inner products of signature (3,1) and (2,2). The objects of investigation are space-like and time-like hyperspheres…
Lie groups as 3-dimensional almost contact B-metric manifolds
Hristo Manev, Dimitar Mekerov
The object of investigations are almost contact B-metric structures on 3-dimensional Lie groups considered as smooth manifolds. There are established the existence and some geometr…
On the structure tensors of almost contact B-metric manifolds
Hristo Manev
The space of the structure (0,3)-tensors of the covariant derivatives of the structure endomorphism and the metric on almost contact B-metric manifolds is considered. A known decom…
