Levi-Civita Ricci-Flat Metrics on Non-Kähler Calabi-Yau Manifolds

open access: closedThe Journal of Geometric Analysis, 2023
In this paper, we provide new examples of Levi-Civita Ricci-flat Hermitian metrics on certain compact non-Kähler Calabi-Yau manifolds, including every compact Hermitian Weyl-Einstein manifold, every compact locally conformal hyperKähler manifold, certain suspensions of Brieskorn manifolds, and every generalized Hopf manifold provided by suspensions of ...

Weak Levi-Civita Connection for the Damped Metric on the Riemannian Path Space and Vanishing of Ricci Tensor in Adapted Differential Geometry

open access: closedJournal of Functional Analysis, 2001
The authors endow the path space over a compact manifold with some adapted Markovian connection \(\nabla\), which takes the curvature tensor into account, is not compatible with the Cameron-Martin metric, but is however compatible with another metric depending on the Ricci tensor (on which no hypothesis is made).

On the geometry of the tangent bundle with gradient Sasaki metric [PDF]

open access: yesArab Journal of Mathematical Sciences, 2023
Purpose – Let (M, g) be a n-dimensional smooth Riemannian manifold. In the present paper, the authors introduce a new class of natural metrics denoted by gf and called gradient Sasaki metric on the tangent bundle TM. The authors calculate its Levi-Civita

Pairs of Associated Yamabe Almost Solitons with Vertical Potential on Almost Contact Complex Riemannian Manifolds

open access: yesMathematics, 2023
Almost contact complex Riemannian manifolds, also known as almost contact B-metric manifolds, are, in principle, equipped with a pair of mutually associated pseudo-Riemannian metrics. Each of these metrics is specialized as a Yamabe almost soliton with a

Quasi-Statistical Schouten–van Kampen Connections on the Tangent Bundle

open access: yesMathematics, 2023
We determine the general natural metrics G on the total space TM of the tangent bundle of a Riemannian manifold (M,g) such that the Schouten–van Kampen connection ∇¯ associated to the Levi-Civita connection of G is (quasi-)statistical.

Non-Linear Friction-Type Behaviors in Liquid Crystals in a Multifractal Paradigm of Motion [PDF]

open access: yesMemoirs of the Scientific Sections of the Romanian Academy, 2022
Fractal analysis of liquid crystals is usually and mainly focused on their intrinsic (structural) properties, and less on their dynamic (functional) properties.
