Sazetak:

The phase structure of different effective quark-meson models for two and
three quark flavors are presented. The impact of the Polyakov loop dynamics
on the phase diagrams is also briefly addressed. All models exhibit a
critical endpoint where fluctuations become important. The influence of
fluctuations around criticality is demonstrated by an comparison of the
mean-field approximation with a renormalization group analysis.
Finally, a novel mean-field treatment of the three flavor quark-meson model
including the axial U(1) anomaly is discussed.
