抄録

The magnitude redshift relation (m-z) in the Brans-Dicke theory with both a variable and constant cosmological term is investigated. Observations of Type Ia Supernovae (SNIa) are used, in the redshift range of 0.01 < z < 2. The contribution of the matter and a variable cosmological term (λ) is examined. As the next approach BDλ model with a constant cosmological term has been investigated. Later Big Bang Nucleosynthesis has been used to constrain the parameters in BDλ model for coupling constant ω = 104.
