Role of Brans-Dicke Theory with or without self-interacting potential in cosmic acceleration

Understand

In this work we have studied the possibility of obtaining cosmic acceleration in Brans-Dicke theory with varying or constant $\omega$ (Brans- Dicke parameter) and with or without self-interacting potential, the background fluid being barotropic fluid or Generalized Chaplygin Gas.

• Here we take the power law form of the scale factor and the scalar field.
• We show that accelerated expansion can also be achieved for high values of $\omega$ for closed Universe.
