Gradient Einstein-type spacetimes and modified gravity

Year: 2025

Type: article

Abstract: In this work, at first, we investigate gradient Einstein-type spacetimes. After that, we study the properties of a gradient Einstein-type spacetime admitting a parallel vector field. In the next parts, we present a systematic study about gradient Einstein-type spacetime obeying f(R, T) and $$f(R,L_m)$$ f ( R , L m ) gravity theories. Finally, in the cosmological context we find some remarkable results.
