Cosmological constraints on time-varying cosmological terms: A study of FLRW universe models with $\Lambda (t)$CDM cosmology

M. Koussour, N. Myrzakulov, J. Rayimbaev

This paper explores models of the FLRW universe that incorporate a time-varying cosmological term $\Lambda (t)$. Specifically, we assume a power-law form for the cosmological term as a fu…
