The parton-cascade model is a microscopic transport approach in the study of the space-time evolution of the quark–gluon plasma produced in relativistic heavy-ion collisions and its experimental manifestations. In the following, parton-cascade calculations on elliptic flow and thermalization will be discussed. Dynamical evolution is shown to be important for the production of elliptic flow including the scaling and the breaking of the scaling of elliptic flow. The degree of thermalization is estimated using both an elastic parton-cascade and a radiative transport model. A longitudinal to transverse pressure ratio of P L /P T ≈0.8 is shown to be expected in the central cell in central collisions. This provides information on viscous corrections to the ideal hydrodynamical approach.
