Description
We summarize recent results on the volume dependence of the location of the critical endpoint in the QCD phase diagram. To this end, we employ a
sophisticated combination of Lattice Yang--Mills theory and a (truncated)
version of Dyson--Schwinger equations in Landau gauge for $2 + 1$ quark
flavours. We study this system at small and intermediate volumes and
determine the dependence of the location of the critical endpoint on the
boundary conditions and the volume of a three-dimensional cube with edge
length $L$. We also discuss quark number fluctuations in this setup.
Additionally, we report on the chiral limit of the light quarks for
different strange quark masses at vanishing chemical potential.
