Non-conserved modified gravity theory
Abstract In the curved spacetime the conservation of stress-energy tensor $${\mathcal {T}}_{\,\,\,\,\, \mu ;\nu }^{\nu }=0$$ T μ ; ν ν = 0 has been questioned by Rastall. However, this idea in which $${\mathcal {T}}_{\,\,\,\,\, \mu ;\nu }^{\nu }=\lambda R_{,\mu }$$ T μ ; ν ν = λ R , μ is own questio...
