European Physical Journal C: Particles and Fields, 2023 We consider dark energy models obtained from the general conformal transformation of the Kropina metric, representing an $$(\alpha , \beta )$$ ( α , β ) -type Finslerian geometry, constructed as the ratio of the square of a Riemannian metric $$\alpha ...

On the coupling of vector fields to the Gauss-Bonnet invariant
, 2015 Inflationary models including vector fields have attracted a great deal of attention over the past decade. Such an interest owes to the fact that they might contribute to, or even be fully responsible for, the curvature perturbation imprinted in the CMB.

Lifshitz from AdS at finite temperature and top down models [PDF]
, 2013 We construct analytically an asymptotically Lifshitz black brane with dynamical exponent z=1+epsilon^2 in an Einstein-Proca model, where epsilon is a small parameter.

CONFORMALLY RECURRENT SPACE-TIMES ADMITTING A PROPER CONFORMAL VECTOR FIELD
Communications of the Korean Mathematical Society, 2014 In this paper we study the properties of conformally recur- rent pseudo Riemannian manifolds admitting a proper conformal vector field with respect to the scalar field , focusing particularly on the 4- dimensional Lorentzian case. Some general properties already proven by one of the present authors for pseudo conformally symmetric manifolds endowed ...

Hidden conformal symmetry for vector field on various black hole backgrounds
Journal of High Energy Physics, 2018 Hidden conformal symmetries of scalar field on various black hole backgrounds have been investigated for years, but whether those features hold for other fields are still open questions. Recently, with proper assumptions, Lunin achieved to the separation

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Conformal vector fields and Yamabe solitons [PDF]
International Journal of Geometric Methods in Modern Physics, 2019 In this paper, we use less topological restrictions and more geometric and analytic conditions to obtain some sufficient conditions on Yamabe solitons such that their metrics are Yamabe metrics, that is, metrics of constant scalar curvature. More precisely, we use properties of conformal vector fields to find several sufficient conditions on the ...
