The model-independent degeneracy-breaking point in cosmological models
  with interacting Dark Energy and Dark Matter
  We study cosmological models with interaction between dark energy (DE) and
dark matter (DM). For the interaction term $Q$ in cosmic evolution equations,
there is a model-independent degeneracy-breaking (D-B) point when $Q_{1}$ (a
part of $Q$) equals to zero, where the interaction can be probed without
degeneracy between the constant DE equation of state (EoS).
