Query: Dynamical Systems analysis of an interacting dark energy model in the
  Brane Scenario   In this paper, we investigate the background dynamics in brane cosmology when
dark energy is coupled to dark matter by a suitable interaction. Here we
consider an homogeneous and isotropic Friedmann-Robertson-Walker (FRW) brane
model and the evolution equations are reduced to an autonomous system by
suitable transformation of variables. The nature of critical points are
analyzed by evaluating the eigenvalues of linearized Jacobi matrix. Finally,
the classical stability of the model is also studied.
