| Abstract: | Exact solutions of the field equations of Nordtvedt’s theory for spatially flat FRW models with constant deceleration parameter
have been obtained. Singular solutions with (i) power-law (ii) exponential expansion have been studied in Nordtvedt’s theory
where the coupling parameterω is a function of the scalar fieldφ. |
