Query: Bianchi type-I dark energy cosmology with power-law relation in
  Brans-Dicke theory of gravitation   In this paper, we have studied the interacting and non-interacting dark
energy and dark matter in the spatially homogenous and anisotropic Bianchi
type-I model in the Brans- Dicke theory of gravitation. The field equations
have been solved by using (i) power-law relation and (ii) by assuming scale
factor in terms of redshift. Here we have considered two cases of an
interacting and non-interacting dark energy scenario and obtained general
results. It has been found that for suitable choice of interaction between dark
energy and dark matter we can avoid the coincidence problem which appears in
the model. Some physical aspects and stability of the models are discussed in
detail. The statefinder diagnostic pair i.e. {r, s} is adopted to differentiate
our dark energy models.
