Abstract

We make a simple observation about two models used to treat the region near the critical temperature of QCD, quasiparticle and matrix models. While they appear very different, we show how these two models might be related. We also present results for the temperature dependence of the ratio of the shear viscosity to the entropy in a matrix model, and suggest that quasi-particle models may behave similarly.
