  ABSTRACT: Based on the Haug-Tatum R H t =ct cosmology model redshift formula, z= R H 0 R H t −1= H t H 0 −1 , we demonstrate that the time-dependent Lambda parameter as a function of z must be Λ t = Λ 0 ( 1+z ) 4 . This equation is also consistent with the Haug and Tatum formula, Λ t =3 H t 2 c 2 =3 ( ℧ T t 2 c ) 2 and the observation-based relation, T t = T 0 ( 1+z ) . We also show how H 0 predicted by the Haug-Tatum model is most consistent with the DESI-based H 0 estimates from the ω 0 ω a CDM model that allows for dynamic dark energy.
