    "abstract": "We study the equation of state of hyperon-rich matter for neutron stars using\nan extended relativistic mean-field model. We take special care of the recently\nproposed non-linear behaviour of the vector field which gives a much better\ndescription of Dirac-Brueckner calculations. The hyperon-hyperon interaction is\nalso implemented by introducing additional meson exchanges. These new terms\navoid the instability found at high densitites in previous works while keeping\nthe excellent description for finite nuclear systems. We also demonstrate\nwithin the mean-field approach that the presence of hyperons inside neutron\nstars on one hand and the hyperon-hyperon interactions on the other hand make\nthe onset of kaon condensation less favourable.",
