Ricci solitons on para-Kähler manifolds

Extracta Mathematicae, 2019
The main purpose of the paper is to study the nature of Ricci soliton on para-Kähler manifolds satisfying some certain curvature conditions. In particular, if we consider certain pseudosymmetric and parallel symmetric tensor on para-Kähler manifolds we

Generalized Cross-Curvature Solitons of 3D Lorentzian Lie Groups

Axioms
We investigate left-invariant generalized cross-curvature solitons on simply connected three-dimensional Lorentzian Lie groups. Working with the assumption that the contravariant tensor Pij (defined from the Ricci tensor and scalar curvature) is ...

Analysis of the Quasi-Concircular Curvature Tensor on Sequential Warped Product Manifolds

Mathematics
This paper investigates the quasi-concircular curvature tensor on sequential warped product manifolds, which extend the classical singly warped product structure.

Geometry of Ricci–Bourguignon Solitons on Mixed Doubly Sequential Warped Products: Existence, Classification, and Cosmological Implications

Axioms
We investigate Ricci–Bourguignon solitons on mixed doubly sequential warped product manifolds. Necessary and sufficient conditions for the existence of such solitons are established, and their implications for Einstein manifolds are analyzed.

Modified F(R,T)-Gravity Model Coupled with Magnetized Strange Quark Matter Fluid

Mathematics
This research note presents the properties of the F(R,T)-gravity model in combination with magnetized strange quark matter. We obtain the equation of state for the magnetized strange quark matter in the F(R,T)-gravity model endowed with the Lagrangian ...

Almost soliton duality

, 2015
Gradient Ricci almost solitons were introduced by Pigola, Rigoli, Rimoldi and Setti [20]. They are defined as solitons except that the metric coefficient is allowed to be a smooth function rather than a constant.

Geometry of Almost Conformal Ricci Solitons on K-Contact Manifolds

Ukrainian Mathematical Journal
UDC 515.1 We study geometric aspects of an almost conformal Ricci soliton and an almost conformal gradient Ricci soliton on K-contact manifolds. Among others, we first obtain the nature of almost conformal Ricci soliton under the conditions: (i) the potential vector field is a contact vector field, and (ii) the potential vector field is pointwise ...

ON RICCI-BOURGUIGNON h-ALMOST SOLITONS IN RIEMANNIAN MANIFOLDS

, 2020
In this paper, we shall give some structure equations for RB h-almost solitons which generalize previous results for Ricci almost solitons. As a consequence of these equations we also derive an integral formula for the compact gradient RB h-almost ...

Modified Ricci flow on a principal bundle [PDF]

, 2008
textLet M be a Riemannian manifold with metric g, and let P be a principal G-bundle over M having connection one-form a. One can define a modified version of the Ricci flow on P by fixing the size of the fiber.
