Özet

We investigate Friedmann-Lamaitre-Robertson-Walker (FLRW) models with modified Chaplygin gas and cosmological constant, using dynamical system methods. We assume p=(gamma-1)mu-A/mu(alpha) as equation of state where mu is the matter-energy density, p is the pressure, alpha is a parameter which can take on values 0
