A perturbative approach on the stability of the Einstein universe in $$f(\mathcal {R},\phi ,\chi )$$ f ( R , ϕ , χ ) gravity
Abstract The aim of this paper is to investigate the stability and existence of the closed Einstein Universe (EU) under linear homogeneous perturbations within the framework of $$ f(\mathcal {R}, \phi , \chi ) $$ f ( R , ϕ , χ ) gravity. For this, we consider a closed Friedmann–Roberson–Walker unive...
