Query: A simplified primal-dual weak Galerkin finite element method for
  Fokker-Planck type equations   A simplified primal-dual weak Galerkin (S-PDWG) finite element method is
designed for the Fokker-Planck type equation with non-smooth diffusion tensor
and drift vector. The discrete system resulting from S-PDWG method has
significantly fewer degrees of freedom compared with the one resulting from the
PDWG method proposed by Wang-Wang \cite{WW-fp-2018}. Furthermore, the condition
number of the S-PDWG method is smaller than the PDWG method \cite{WW-fp-2018}
due to the introduction of a new stabilizer, which provides a potential for
designing fast algorithms. Optimal order error estimates for the S-PDWG
approximation are established in the $L^2$ norm. A series of numerical results
are demonstrated to validate the effectiveness of the S-PDWG method.
