Constructing viable interacting dark matter and dark energy models: a dynamical systems approach

Ashmita,
Kinjal Banerjee,
Prasanta Kumar Das

Abstract: We study the evolution of k = -1 FLRW cosmological models for two interacting Dark Matter-Dark Energy Models using dynamical system analysis. Since we are interested in late time evolution, the sign of the interaction term is chosen such that it facilitates the transfer of energy from dark matter to dark energy. We also explore the k = 0 invariant subspace of these models. We find that both these models have sectors which have a stable fixed point where we can recover an accelerating universe with a negative … Show more
