Low-Concentration Electrolytes Based on Weakly Coordinating Anions for Applications in Lithium-Ion-Batteries and Lithium-Metal-Batteries. [PDF]

open access: yesAngew Chem Int Ed Engl
Big is beautiful? The performance of 0.2 M low concentration lithium electrolytes with large weakly coordinating anions [Al{OC(CF3)3}4]− and [Ga(C2F5)4]− in low viscosity ortho‐difluorobenzene solution is tested in comparison to standard 1.0 M as well as diluted 0.2 M carbonate‐based electrolytes with Li[PF6] conducting salt.

Geometry of Indefinite Kenmotsu Manifolds as *η-Ricci-Yamabe Solitons

open access: yesAxioms, 2022
In this paper, we study the properties of ϵ-Kenmotsu manifolds if its metrics are *η-Ricci-Yamabe solitons. It is proven that an ϵ-Kenmotsu manifold endowed with a *η-Ricci-Yamabe soliton is η-Einstein. The necessary conditions for an ϵ-Kenmotsu manifold,

Certain Curvature Conditions on Kenmotsu Manifolds and 🟉-η-Ricci Solitons

open access: yesAxioms, 2023
The present paper deals with the investigations of a Kenmotsu manifold satisfying certain curvature conditions endowed with 🟉-η-Ricci solitons. First we find some necessary conditions for such a manifold to be φ-Einstein. Then, we study the notion of 🟉-η-

The conformal sector of Quantum Einstein Gravity beyond the local potential approximation

open access: yesPhysics Letters B, 2023
The anomalous scaling of Newton's constant around the Reuter fixed point is dynamically computed using the functional flow equation approach. Specifically, we thoroughly analyze the flow of the most general conformally reduced Einstein-Hilbert action ...

Conformal η-Ricci Solitons on Riemannian Submersions under Canonical Variation

open access: yesAxioms, 2022
This research article endeavors to discuss the attributes of Riemannian submersions under the canonical variation in terms of the conformal η-Ricci soliton and gradient conformal η-Ricci soliton with a potential vector field ζ.

Some solitons on anti-invariant submanifold of LP-Kenmotsu manifold admitting Zamkovoy connection [PDF]

open access: yesJournal of Hyperstructures
In this paper we prove some curvature properties of anti-invariant submanifold of Lorentzian para-Kenmotsu manifold (briefly, LP-Kenmotsu manifolds) with respect to Zamkovoy connection (∇∗).

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

open access: yesMathematics, 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.

Conformal η-Ricci-Yamabe Solitons within the Framework of ϵ-LP-Sasakian 3-Manifolds

open access: yesAdvances in Mathematical Physics, 2022
In the present note, we study ϵ-LP-Sasakian 3-manifolds M3ϵ whose metrics are conformal η-Ricci-Yamabe solitons (in short, CERYS), and it is proven that if an M3ϵ with a constant scalar curvature admits a CERYS, then £Uζ is orthogonal to ζ if and only if

The Generalized Hartle-Hawking Initial State: Quantum Field Theory on Einstein Conifolds [PDF]

open access: yes, 1999
Recent arguments have indicated that the sum over histories formulation of quantum amplitudes for gravity should include sums over conifolds, a set of histories with more general topology than that of manifolds.
