  We prove local well-posedness for the Vlasov-Poisson-Landau system and the
variant with massless electrons in a 3D periodic spatial domain for large
initial data. This is accomplished by propagating weighted anisotropic L2-based
Sobolev norms. In the case of the massless electron system, we also carry out
an analysis of the Poincare-Poisson system. This is a companion paper to the
author's previous work with Yan Guo.
