    Overturning and cracking of stellar objects in modified $$f(R, \varphi )$$ f ( R , φ ) gravity by Adnan Malik, Attiya Shafaq, Fatemah Mofarreh, M. Farasat Shamir, Wedad Albalawi

    Published 2025-02-01
    “…Abstract This study extends the concept of cracking to self-gravitating, spherically symmetric compact objects in modified $$f(R, \varphi )$$ f ( R , φ ) theory of gravity, where R represents the Ricci scalar, and $$\varphi $$ φ is the scalar potential. …”

    The Palatini formalism of the $$f(R,{\mathcal {L}}_{m},T)$$ f ( R , L m , T ) theory of gravity by J. G. de Lima, P. H. R. S. Moraes, E. Brito, J. A. S. Fortunato

    Published 2025-01-01
    “…Abstract We present the first formulation of the recently proposed $$f(R,{\mathcal {L}}_m,T)$$ f ( R , L m , T ) theory of gravity within the Palatini formalism, a well-known alternative variational approach where the metric and connection are treated as independent variables. …”

    Stationary BTZ space-time in Ricci-inverse and $$f({\mathcal {R}})$$ f ( R ) gravity theories by Faizuddin Ahmed, Abdelmalek Bouzenada

    Published 2024-12-01
    “…We consider a general class of this gravity theory, where the function f is defined by $$f({\mathcal {R}}, {\mathcal {A}}, A^{\mu \nu }\,A_{\mu \nu })$$ f ( R , A , A μ ν A μ ν ) , with $${\mathcal {R}}$$ R and $${\mathcal {A}}$$ A representing the Ricci and anti-curvature scalars, respectively and $$A^{\mu \nu }$$ A μ ν is the anti-curvature tensor. …”

    The product of r−k and ∇δ on ℝm by C. K. Li

    Published 2000-01-01
    “…Cheng and Li (1991) utilized a net δϵ(x) (similar to the δn(x)) and the normalization procedure of μ(x)x+λ to deduce a commutative neutrix product of r−k and δ for any positive real number k. The object of this paper is to apply Pizetti's formula and the normalization procedure to derive the product of r−k and ∇δ (∇ is the gradient operator) on ℝm. …”
