Ricci-like Solitons with Arbitrary Potential and Gradient Almost Ricci-like Solitons on Sasaki-like Almost Contact B-metric Manifolds

Results in Mathematics, 2022
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 the vertical component of both B-metrics multiplied by a constant. It is established that gradient almost Ricci-like solitons have constant soliton coefficients.

The components of the structure tensor of five-dimensional almost contact B-metric manifolds

Asian-European Journal of Mathematics, 2020
Almost contact [Formula: see text]-metric manifolds of the dimension 5 are considered. Our aim is to determine the corresponding components of the structure tensor of these manifolds. Some known examples of almost contact [Formula: see text]-metric manifolds are commented.

Curvature properties of normal almost contact manifolds with B-metric

Journal of Geometry, 2013
Let \(M\) be a \((2n+1)\)-dimensional manifold equipped with an almost contact structure \((\varphi,\xi,\eta)\) and a pseudo-Riemannian metric \(g\) such that \( g(\varphi x,\varphi y ) = - g(x,y) + \eta(x)\eta(y) \) for vector fields \(x,y,z, \dots\) on \(M\), i.e., a \(B\)-metric.

Submanifolds of some almost contact manifolds with \(B\)-metric with codimension two. II

1998
Summary: The authors study submanifolds of almost contact manifolds with \(B\)-metric of codimension 2, such that the vector field of the almost contact structure does not belong to the tangential space or to be normal space of the submanifold. Examples of such submanifolds are constructed.
