Description
We solve the one-dimensional boost-invariant kinetic equation for a relativistic massive
system with the collision term treated in the relaxation time approximation. The result
is an exact integral equation which can be solved numerically by the method of iteration
to arbitrary precision. We compare predictions for the shear and bulk viscosities of a
massive system with those obtained from the exact solution. Finally, we compare the time
evolution of the bulk pressure obtained from our exact solution with results obtained from
the dynamical equations of second-order viscous hydrodynamics.
