Abstract : The aim of this paper is to show local well-posedness of 2 dimensional Dirac equations with honeycomb lattice nonlinearity and Hartree type nonlinearity in $H^s$ for $s>\frac38$ and $s>\frac78$, respectively. To this end, we use a bilinear estimate derived from Selberg's argument(\cite{sel}). We also provide the smoothness failure of flows of Dirac equations.
Keywords : Dirac equations, Honeycomb lattice, local well-posedness, non-smoothness, Bourgain's space.
