  In this paper we address the derivation of causal relativistic hydrodynamics,
formulated within the framework of Divergence Type Theories (DTTs), from
kinetic theory for spinless particles obeying Fermi-Dirac statistics. The
approach leads to expressions for the particle current and energy momentum
tensor that are formally divergent, but may be given meaning through a process
of regularization and renormalization. We demonstrate the procedure through an
analysis of the stability of an homogeneous anisotropic configuration. In the
DTT framework, as in kinetic theory, these configurations are stable. By
contrast, hydrodynamics as derived from the Grad approximation would predict
that highly anisotropic configurations are unstable.
