“…Also, many authors like Singh and Rai [7], Mukherjee [8], Reddy and Naidu [9], Venkateswarlu et al [10,11] had investigated various aspects of cosmological models in a different context with the Sen-Dunn scalar-tensor theory of gravitation. Ghate and Sontakke [12] studied Bianchi type-IX dark energy model in the Sen-Dunn theory of gravitation. Patra [13] also studied the string cosmological model in a new scalar-tensor theory of gravitation.…”
