Para-Ricci-Like Solitons on Riemannian Manifolds with Almost Paracontact Structure and Almost Paracomplex Structure [PDF]

Mathematics, 2021
We introduce and study a new type of soliton with a potential Reeb vector field on Riemannian manifolds with an almost paracontact structure corresponding to an almost paracomplex structure.

Para-Ricci-like Solitons with Arbitrary Potential on Para-Sasaki-like Riemannian Π-Manifolds

Mathematics, 2022
Para-Ricci-like solitons with arbitrary potential on para-Sasaki-like Riemannian Π-manifolds are introduced and studied. For the studied soliton, it is proved that its Ricci tensor is a constant multiple of the vertical component of both metrics.

Metallic deformation on para-Sasaki-like para-Norden manifold

AIMS Mathematics
<p>The main goal of this paper is to define the concept of metallic deformation through a relation between the metallic structure and paracontact structure on an almost paracontact para-Norden manifold. A Riemannian connection is obtained on a metallically deformed para-Sasaki-like para-Norden manifold.

Para-Sasaki-like Riemannian manifolds with generalized symmetric metric connection

Filomat
The present paper deals with the generalized symmetric metric connection defined on para-Sasaki-like Riemannian manifolds. We derive a relation between the Levi-Civita connection and the generalized symmetric metric conneciton on the considered manifold.

Para-Sasaki-like Manifolds with Generalized Symmetric Metric Connection

, 2023
The present paper deals with the generalized symmetric metric connection defined on para-Sasaki-like manifolds. We derive a relation between the Levi-Civita connection and the generalized symmetric metric conneciton on the considered manifold. We investigate the curvature tensor, the Ricci tensor and scalar curvature tensor with respect to the ...
