Abstract. This talk deals with the well-posedness and asymptotic analysis on a Cahn-Hilliard phase field system arising from tumor growth models on a bounded or an unbounded domain with smooth bounded boundary.
The system consists of three diffusive equations in terms of the variables representing order parameter, chemical potential and concentration; it has been recently investigated in the case of a bounded domain by exploiting the Aubin-Lions lemma for the limit procedure. However, this lemma does not work directly in the case of unbounded domains. In our approach we can discuss a vanishing viscosity process for the above system both in the case of bounded domains and in the case of an unbounded domain.
