| Popis: | In this work, we establish a model of holographic dark energy interacting with dark matter in flat Friedmann-Lemaitre-Robertson-Walker (FLRW) universe and test this model with observational data of Type-Ia supernovae (SNeIa), baryon acoustic oscillation (BAO), cosmic microwave background (CMB) anisotropy and Hubble parameter $H(z)$ . Next we obtain the deceleration parameter and the coincidence parameter and solve the coincidence problem. |
