Zusammenfassung: As examples, we consider compressible Euler systems with and without additional Poisson equation. There are various mechanisms which can make the flow incompressible, such as the low Mach number limit, or the quasi-neutral limit in case of systems of transport of electrically charged particles. The talk presents a general functional analytical framework for handling all these limits, in the context of symmetrisable systems. The key idea is to choose an operator-valued symmetrising matrix.
