Pair of associated Schouten-van Kampen connections adapted to an almost paracontact almost paracomplex Riemannian structure
Hristo Manev, Mancho Manev
There are introduced and studied a pair of associated Schouten-van Kampen affine connections adapted to the paracontact distribution and an almost paracontact almost paracomplex Ri…
Hyperspheres in Euclidean and Minkowski 4-spaces as almost paracontact almost paracomplex Riemannian manifolds
Mancho Manev, Veselina Tavkova
Almost paracontact almost paracomplex Riemannian manifolds of the lowest dimension are studied. Such structures are constructed on hyperspheres in 4-dimensional spaces, Euclidean a…
Para-Sasaki-like Riemannian manifolds and new Einstein metrics
Stefan Ivanov, Hristo Manev, Mancho Manev
We extract a new class of paracontact paracomplex Riemannian manifolds arising from certain cone construction, call it para-Sasaki-like Riemannian manifold and give explicit exampl…
Almost Ricci-like solitons with torse-forming vertical potential of constant length on almost contact B-metric manifolds
Mancho Manev
A generalization of Ricci-like solitons with torse-forming potential, which is a constant multiple of the Reeb vector field, is studied. The conditions under which these solitons a…
Matrix Lie Groups as 3-Dimensional Almost Paracontact Almost Paracomplex Riemannian Manifolds
Mancho Manev, Veselina Tavkova
Lie groups considered as three-dimensional almost paracontact almost paracomplex Riemannian manifolds are investigated. In each basic class of the classification used for the manif…
Ricci-like solitons with arbitrary potential and gradient almost Ricci-like solitons on Sasaki-like almost contact B-metric manifolds
Mancho Manev
Ricci-like solitons with arbitrary potential are introduced and studied on Sasaki-like almost contact B-metric manifolds. It is proved that the Ricci tensor of such a soliton is th…
Ricci-like solitons with vertical potential on Sasaki-like almost contact B-metric manifolds
Mancho Manev
Ricci-like solitons on Sasaki-like almost contact B-metric manifolds are the object of study. Cases, where the potential of the Ricci-like soliton is the Reeb vector field or point…
