Casorati Inequalities for Spacelike Submanifolds in Sasaki-like Statistical Manifolds with Semi-Symmetric Metric Connection

Mathematics, 2022
In this paper, we establish some inequalities between the normalized δ-Casorati curvatures and the scalar curvature (i.e., between extrinsic and intrinsic invariants) of spacelike statistical submanifolds in Sasaki-like statistical manifolds, endowed ...

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.

Pair of Associated η-Ricci–Bourguignon Almost Solitons with Vertical Potential on Sasaki-like Almost Contact Complex Riemannian Manifolds

Mathematics
The manifolds studied are almost contact complex Riemannian manifolds, known also as almost contact B-metric manifolds. They are equipped with a pair of pseudo-Riemannian metrics that are mutually associated to each other using an almost contact ...

Pair of Associated η-Ricci–Bourguignon Almost Solitons with Generalized Conformal Killing Potential on Sasaki-like Almost Contact Complex Riemannian Manifolds

Mathematics
The subject of this study is almost contact complex Riemannian manifolds, also known as almost contact B-metric manifolds. The considerations are restricted to a special class of these manifolds, namely those of the Sasaki-like type, because of their ...

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

Mathematics, 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

Cell-type-specific gating of gene regulatory modules as a hallmark of early immune responses in Arabidopsis leaves. [PDF]

New Phytol
Summary In plants, multiple cell types contribute to immunity, but what division of labor exists among cell types when immunity is activated? We compared, at single‐cell resolution, the response of Arabidopsis thaliana leaf cells during pattern‐triggered and effector‐triggered immunity (PTI/ETI), sampled at 3 and 5 h after infection with Pseudomonas ...

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.

Constancy of ?-holomorphic sectional curvature of an indefinite Sasaki-like almost contact manifold with B-metric

New Trends in Mathematical Science, 2018
The aim of the present paper is to establish a criterion for an indefinite Sasaki-like almost contact manifold with B-metric to reduce to a space of φ-holomorphic sectional curvature.

Anisotropic conformal dark gravity on the Lorentz tangent bundle spacetime [PDF]

Physical Review D, 2023
In this work we investigate the anisotropic conformal structure of the gravitational field incorporating dark gravity in a generalized Lagrange geometric framework on the Lorentz tangent bundle and we present two applications; the anisotropic conformal ...
