Comparative Study of Early-Universe Epochs in an $f (R, L_{m})$ Gravity Model with Effective Curvature--Matter Interaction and $I^$ CDM Cosmology

G. K. Goswami, J. P. Saini

We investigate a specific gravity model of the form $f (R, L_{m}) = I^\pm R + L_{m}^{2} + I^^{3}$ , where the nonlinear dependence on the matter Lagrangian $L_{m}$ introduces an effective curvature…

Growth Rate Analysis in $f (R, L_{m})$ Gravity: A Comparative Study with \boldmath $I^$ CDM Cosmology

G. K. Goswami, J. P. Saini

We investigate the evolution of cosmic structures within the framework of modified gravity, specifically focusing on theories described by the function $f (R, L_{m})$ , where $R$ is th…
